If your network feels sluggish, you're not alone. After years of battling slow connections, dropped calls, and frustrated end-users, I’ve learned one thing: network performance issues always have a root cause.

Maybe your VoIP calls keep cutting out. Maybe cloud apps take forever to load. Or maybe your team complains about "the network being slow" β€” again. The problem? Networks don’t slow down for no reason. Something’s eating your bandwidth, choking your latency, or overloading your hardware.

The good news? Most issues boil down to 10 key factors killing your network performance. Understand these, and you can stop guessing β€” and start fixing.

Factor #1. Bandwidth vs. Throughput: The Real Difference (And Why It Matters for Network Performance)
Factor #1. Bandwidth vs. Throughput: The Real Difference (And Why It Matters for Network Performance)

If your network feels slow despite having "high-speed" Internet, bandwidth and throughput are the first things to check. Many IT teams (and even some providers) use these terms interchangeably, but they’re not the same thing.

Bandwidth: Your Network’s Speed Limit
Bandwidth: Your Network’s Speed Limit

Think of bandwidth like a highway:

  • More lanes (higher bandwidth) = More cars (data) can move at once.
  • Measured in Mbps (Megabits per second) or Gbps (Gigabits per second).

But here’s the catch: Bandwidth is just potential speed. It doesn’t guarantee how much data actually gets through.

factors affecting network performance - Bandwidth

Throughput: The Reality of Your Network’s Performance
Throughput: The Reality of Your Network’s Performance

Throughput is what you actually get β€” the real-world data transfer rate after accounting for:

  • Network congestion (too many users/apps fighting for bandwidth).
  • Protocol overhead (TCP/IP, encryption, packet headers eating up capacity).
  • Latency and packet loss (retransmissions slowing things down).

Example: The Highway vs. Traffic Jam

  • Bandwidth = 4 lanes (100 Mbps).
  • Throughput = Only 1 lane open due to congestion (25 Mbps).

factors affecting network performance - Throughput

Why Does the Gap Between Bandwidth and Throughput Happen?
Why Does the Gap Between Bandwidth and Throughput Happen?

Several factors can throttle your throughput below your max bandwidth:

Factor β†’ Impact

  • Network congestion β†’ Too many devices/apps saturate available bandwidth.
  • Protocol overhead β†’ VPNs, encryption, and packet headers consume ~10-20% of bandwidth.
  • Packet loss β†’ Dropped packets force retransmissions, reducing effective speed.
  • Latency β†’ High delay means slower acknowledgment of received data.
  • ISP throttling β†’ Some providers artificially limit speeds during peak times.

How to Fix Bandwidth vs. Throughput Issues
How to Fix Bandwidth vs. Throughput Issues

  1. Run a Speed Test (But Do It Right)
    • Use tools like Obkio’s Network Speed Test (not just Ookla) to measure real throughput under load.
    • Test at different times (peak vs. off-peak) to spot ISP throttling.
  2. Identify Bandwidth Hogs
    • Check which apps/users consume the most bandwidth (Netflix? Cloud backups?).
    • Use QoS (Quality of Service) to prioritize critical traffic (VoIP, video calls).
  3. Upgrade (If Necessary)
    • If throughput is consistently <70% of bandwidth, investigate congestion or ISP issues.
    • For businesses, consider SD-WAN to dynamically route traffic efficiently.

When More Bandwidth Isn’t the Answer?

Adding bandwidth doesn’t always fix throughput problems if:

  1. Your router can’t handle the load (check CPU/memory usage).
  2. You have latency/jitter issues (common in VoIP/video calls).
  3. Wi-Fi interference is the real bottleneck.

Key Takeaway: Don’t Just Check Bandwidth β€” Measure Throughput

Factor #2. Latency: The Silent Killer of Real-Time Apps
Factor #2. Latency: The Silent Killer of Real-Time Apps

Nothing kills productivity faster than that dreaded lag β€” when your video call freezes mid-sentence or your cloud app hangs just as you're about to save. That's latency at work, and in today's real-time digital world, even milliseconds matter.

What Exactly Is Latency?
What Exactly Is Latency?

Latency is the delay between sending data and getting a response, like the pause between saying "Hello?" and hearing "Hi!" during a phone call.

Measured in milliseconds (ms)

  • Under 50ms = Smooth experience (ideal for VoIP, video calls, gaming)
  • 50 - 150ms = Noticeable delay (annoying but workable)
  • Over 150ms = "Hello? Are you still there?" territory

factors affecting network performance - Latency

Why Latency Matters More Than Ever
Why Latency Matters More Than Ever

A decade ago, a half-second delay in loading a webpage was tolerable. Today, with remote work, cloud apps, and real-time collaboration tools, high latency directly impacts:

βœ” VoIP & video conferencing (choppy audio, frozen video)

βœ” Cloud applications (laggy Salesforce, slow SaaS tools)

βœ” Online gaming & trading (where milliseconds = wins or losses)

Fixing High Latency: 5 Proven Solutions
Fixing High Latency: 5 Proven Solutions

1. Optimize Physical Distance

  • Use CDNs (Content Delivery Networks) for global teams
  • Choose cloud regions closest to users

2. Reduce Network Hops

  • Fix inefficient routing (avoid "trombone routing" where traffic backtracks)
  • Consider SD-WAN to dynamically pick the fastest path

3. Ditch Wi-Fi for Critical Apps

  • Use Ethernet for VoIP phones, trading terminals
  • If Wi-Fi is a must, upgrade to Wi-Fi 6 and optimize placement

4. Prioritize Traffic with QoS

  • Give VoIP, video calls, and business apps top priority
  • Throttle bandwidth-heavy backups/updates during work hours

5. Upgrade Aging Infrastructure

  • Replace old routers/switches adding processing delay
  • Check fiber vs. copper (fiber often has lower latency)

Factor #3. Jitter & Packet Loss: Why Your Calls Sound Like Robots
Factor #3. Jitter & Packet Loss: Why Your Calls Sound Like Robots

There's nothing more frustrating than a VoIP call where:

βœ” Every third word cuts out

βœ” The audio stutters like a glitchy robot

βœ” The video freezes mid-sentence

This isn't just "bad Internet" β€” it's jitter and packet loss wreaking havoc on your real-time communications. And while we're focusing on calls here because they're the most sensitive to jitter and packet loss (even the smallest amount can cause issues), the truth is that jitter and packet loss affect all your network applications and Internet performance β€” they just do so at different levels.

Real-world analogy:

Imagine mailing 10 letters (data packets) to a friend:

  • Jitter = Letters arrive on random days (Tuesday, Friday, Monday...)
  • Packet Loss = Some letters never show up

factors affecting network performance - Packet Loss

Let's break down why this happens and how to fix it for good.

Why Jitter & Packet Loss Destroy VoIP/Video Calls
Why Jitter & Packet Loss Destroy VoIP/Video Calls

Real-time apps hate inconsistency. Unlike email or file downloads (which can retry), VoIP and video:

βœ” Require packets to arrive in order (or the audio/video desyncs)

βœ” Need consistent timing (human ears notice even 50ms variations)

βœ” Have no time to retry (lost packets = dead air)

Result:

  • Jitter > 30ms = Robotic, stuttering audio
  • Packet Loss > 1% = Gaps in conversation, frozen video

Top 5 Causes of Jitter and Packet Loss (and How to Test for Them)
Top 5 Causes of Jitter and Packet Loss (and How to Test for Them)

1. Network Congestion (The Usual Suspect)

What happens: Packets get stuck in router buffers, arriving late (jitter) or being dropped (packet loss)

How to test:

2. Wi-Fi Woes (Silent Killer of Calls)

What happens: Wireless interference causes retransmissions β†’ inconsistent delays

How to test:

  • Compare Ethernet vs. Wi-Fi jitter (spoiler: Wi-Fi is often 2-3x worse)

3. Bad QoS (Or None at All)

What happens: Netflix 4K streams steal bandwidth from your Zoom calls

How to test:

  • Check if real-time traffic (SIP, RTP) is prioritized in router QoS settings

4. Faulty Hardware (Cables, Routers, Switches)

What happens: A flaky Ethernet cable or overloaded router drops packets

How to test:

  • Swap hardware components one by one while monitoring packet loss

5. ISP/Peering Issues (When It's Not Your Fault)

What happens: Packet loss occurs outside your network (ISP backbone issues)

How to test:

  • Use Obkio’s Public Agents to measure loss to multiple endpoints

How to Fix Packet Loss & Jitter (From a Network Engineer’s Playbook)
How to Fix Packet Loss & Jitter (From a Network Engineer’s Playbook)

  1. For Jitter:

    βœ” Enable QoS (Prioritize VoIP/video traffic over less sensitive apps)

    βœ” Upgrade to Ethernet (Wi-Fi jitter is unpredictable)

    βœ” Use Jitter Buffers (Some VoIP systems can compensate for 20-50ms jitter)

  2. For Packet Loss:

    βœ” Enable FEC (Forward Error Correction) (VoIP tech that reconstructs lost packets)

    βœ” Switch Codecs (Use loss-tolerant ones like Opus instead of G.711)

    βœ” Check Physical Links (Replace damaged cables, reboot flaky switches)

  3. When All Else Fails:

    βœ” SD-WAN (Dynamically routes calls over the most stable connection)

    βœ” Dedicated VoIP VLAN (Isolates call traffic from other bandwidth hogs)

Key Takeaway: Jitter and Packet loss won’t fix themselves.
Key Takeaway: Jitter and Packet loss won’t fix themselves.

The solution?

βœ… Monitor continuously (not just when users complain)

βœ… Isolate the cause (Wi-Fi? ISP? Congestion?)

βœ… Prioritize real-time traffic (QoS is non-negotiable)

Factor #4. Network Monitoring and Troubleshooting: Stop Flying Blind

Here’s the truth: Your users shouldn’t be your network monitoring system.

If you’re only finding out about network issues when the helpdesk phone starts ringing, you’re already losing. The difference between a proactive IT team and a firefighting IT team comes down to one thing: continuous monitoring of factors affecting network performance.

Why Traditional Network Monitoring Fails (And What Works Instead)
Why Traditional Network Monitoring Fails (And What Works Instead)

Most companies monitor their networks in one of two outdated ways:

  1. The "Ping and Pray" Method

    ❌ Checks if devices are up/down (but not performance)

    ❌ Misses latency spikes, jitter, packet loss

    ❌ No historical data to spot trends

  2. The "Wait for Complaints" Strategy

    ❌ Users report issues after productivity is lost

    ❌ No visibility into root causes (just "the network is slow!")

    ❌ Leads to blame games between teams

Modern Network Monitoring: How It Actually Works

The way you monitor your network directly impacts how well it performs and how effectively it’s maintained. If you're proactively monitoring your network, it means you can identify issues faster, minimize downtime, and ensure better overall performance. But if you're only discovering problems once they've already escalated, performance plummets β€” and your network could stay down much longer.

Proactive teams use continuous performance monitoring that:

βœ” Simulates real user traffic using synthetic UDP traffic (tests VoIP, video, cloud apps)

βœ” Continuously measures network metrics that matter (latency, jitter, packet loss, throughput)

βœ” Stores historical data to identify patterns (e.g., "Every Tuesday at 3 PM, latency spikes") β€” and tracks performance against thresholds to detect even the smallest changes that could indicate a problem

Example: Obkio’s monitoring agents act like virtual users running constant tests between offices, clouds, and data centers β€” so you see problems before employees do.

This is Obkio’s method to ensure you’re monitoring end-to-end network performance β€” from every critical point in your network path. While not all network monitoring tools use agents, Obkio’s agent-based approach gives you deeper visibility into performance from the user’s perspective.

Free Trial - Banner - Generic

Step 1: Deploy Monitoring Agents

  • Place agents in key locations (HQ, branches, cloud VMs)
  • Use public agents to test ISP/Internet performance

Step 2: Define Critical Metrics

You shouldn’t have to define every metric yourself β€” a good network monitoring tool does that for you. It continuously measures all the key metrics like jitter, packet loss, latency, and throughput, and tells you which ones are affecting which parts of your network. That way, you can focus on solving issues.

Step 3: Configure Proactive Alerts for Network Issues

  • Configure alerts based on thresholds depending on the sensitivity of your key applications
  • Avoid alert fatigue (only notify on real issues)

Example: "Alert if latency to Azure jumps >50% from baseline"

Step 4: Review Daily (10 Minutes Max)

  • Check performance dashboards with coffee
  • Investigate any anomalies before they escalate

Real-world savings:

  • 50% fewer "network is slow" tickets
  • 80% faster mean-time-to-repair (MTTR)

Factor #5. Too Many Devices Causing Network Congestion
Factor #5. Too Many Devices Causing Network Congestion

You know that moment when your network suddenly feels like a congested highway at rush hour?

Your network wasn't designed for today's device explosion. Between smartphones, IoT gadgets, and shadow IT, most corporate networks are drowning under connections they were never meant to handle. So, how does the number of devices affect network performance?

The Hidden Cost of Device Sprawl
The Hidden Cost of Device Sprawl

Every new device on your network:

βœ” Consumes bandwidth (even when "idle")

βœ” Increases broadcast traffic (ARP, DHCP chatter)

βœ” Adds load to routers/switches (more MAC tables, more CPU usage)

Real-world example:

A "normal" office that once had 50 devices now has:

  • 75 company laptops
  • 120 employee phones/tablets
  • 30 IoT devices (printers, cameras, smart TVs)
  • 20+ unauthorized "shadow IT" gadgets

Result? Network performance degrades by 40%+ during peak hours.

How to Detect Device Overload
How to Detect Device Overload

1. Monitor Network Device Performance

  • Router/switch CPU/memory usage (consistently >70% = bottleneck)
  • ARP table sizes (older switches may struggle with 1000+ devices)
  • Broadcast storm detection (excessive chatter slows everything down)

Pro Tip: Use a network device monitoring tool to track these metrics automatically.

2. Identify Bandwidth Hogs

  • Top talkers list (which devices consume most bandwidth?)
  • Unusual traffic patterns (e.g., a "smart fridge" using 5Mbps constantly)

3. Check Authentication Logs

  • Rogue devices (personal gadgets on corporate WiFi)
  • Orphaned connections (old devices still authenticated but unused)

5 Fixes That Actually Work
5 Fixes That Actually Work

1. Network Segmentation (The VLAN Solution)

Separate traffic types:

  • Corporate devices (high priority)
  • Guest WiFi (limited bandwidth)
  • IoT (isolated VLAN with no internal access)

2. Implement 802.1X Authentication

  • Blocks unauthorized devices from connecting
  • Automatically quarantines non-compliant devices

3. Set Device Limits Per User

  • Max 3 devices per employee (laptop + phone + tablet)
  • Require approval for additional connections

4. Schedule Bandwidth-Heavy Tasks

  • After-hours updates (Windows patches, backups)
  • QoS policies to throttle non-critical traffic during work hours

5. Upgrade Legacy Hardware

Old switches may struggle with:

  • 500 MAC addresses
  • Gigabit+ throughput
  • Modern encryption (WPA3, etc.)

When to Consider Advanced Solutions

βœ” Microsegmentation (for zero-trust networks)

βœ” AI-driven device profiling (automatically classify/restrict devices)

βœ” SD-WAN (to prioritize critical traffic across locations)

Key Takeaway: Don't Just Add Bandwidth β€” Add Control
Key Takeaway: Don't Just Add Bandwidth β€” Add Control

More bandwidth won't fix device congestion if:

Factor #6. Network Traffic Types: Why Your Network Hates Video Calls

You’ve probably seen this happen:

  • 9 AM: Network runs smoothly.
  • 10 AM Standup: Video calls start freezing.
  • 2 PM Backup Job: File transfers crawl to a halt.

This isn’t magic β€” it’s your network struggling with different traffic types. Not all data is equal, and if you treat a Zoom call the same as a Windows update, you’re in for a world of pain.

The 6 Traffic Types Crushing Your Network
The 6 Traffic Types Crushing Your Network

1. High-Bandwidth Hogs (The Bandwidth Bullies)

Examples: Video streaming (YouTube, Netflix), large file transfers

Why They’re Problematic:

  • Can consume 90%+ of available bandwidth if unchecked
  • Leave no room for critical apps (VoIP, CRM, cloud tools)

2. Real-Time Traffic (The Divas of Networking)

Examples: VoIP calls (MS Teams, Zoom), video conferencing, online gaming

What They Demand:

  • Low latency (<50ms)
  • Zero jitter (<30ms variation)
  • No packet loss (<1%)

factors affecting network performance - network traffic

3. Bulk Data Transfers (The Silent Killers)

Examples: Cloud backups, Windows updates, database syncs

Why They Cause Chaos:

  • Often run unnoticed in the background
  • Can saturate bandwidth for hours if not scheduled

4. Small but Frequent Packets (The Switch Overloaders)

Examples: IoT sensors, VoIP control traffic, DNS queries

The Hidden Impact:

  • Each packet requires router/switch processing
  • 10,000 tiny packets = more CPU load than one big file

5. Encrypted Traffic (The Necessary Evil)

Examples: VPNs, HTTPS, secure cloud apps

The Trade-Off:

  • Security benefit: Data is protected
  • Performance cost: Encryption/decryption adds 10-20% more CPU load

6. Malicious Traffic (The Uninvited Guests)

Examples: DDoS attacks, spam, port scans

How They Hurt You:

  • Waste precious bandwidth on junk traffic
  • Trigger false congestion alerts

5 Ways to Tame Your Network Traffic
5 Ways to Tame Your Network Traffic

1. Quality of Service (QoS) – Your Traffic Cop

  • Prioritize real-time traffic (VoIP, video calls)
  • Throttle bandwidth hogs (Netflix, backups)
  • Example Rule: "VoIP gets 30% guaranteed bandwidth 8AM-6PM"

2. Schedule Bulk Transfers for Off-Peak

  • After-hours backups (7PM-6AM)
  • Weekend updates (when office is empty)

3. Segment Your Network

Separate traffic types with VLANs:

  • Voice VLAN (high priority)
  • Guest WiFi (limited speed)
  • IoT VLAN (Internet-only)

4. Optimize Encryption Overhead

  • Upgrade hardware to handle modern encryption (AES-NI support)
  • Balance security/performance (WPA3 for WiFi, but QoS for VoIP)

5. Monitor and Block Malicious Traffic

  • Detect DDoS/spam with network monitoring
  • Auto-block suspicious IPs (fail2ban, firewall rules)

Key Takeaway: Not All Network Traffic Is Equal
Key Takeaway: Not All Network Traffic Is Equal

βœ… Real-time apps (VoIP, video) must be prioritized.

βœ… Bandwidth hogs (streaming, backups) must be controlled.

βœ… Malicious traffic must be blocked.

5 Fixes For Solving Network Congestion
5 Fixes For Solving Network Congestion

1. Implement Smart Queuing (QoS on Steroids)

  • Prioritize business-critical traffic (VoIP, CRM, video calls)
  • Limit bandwidth hogs (streaming, backups)
  • Example: Give Zoom 5Mbps guaranteed, cap Netflix at 2Mbps

2. Enable Explicit Congestion Notification (ECN)

  • Lets devices slow down gracefully before packet loss happens
  • Supported in modern TCP stacks (Windows 10+, Linux)

3. Fix Bufferbloat

  • Use fq_codel or CAKE queuing disciplines
  • Reduces latency spikes from 1000ms+ to <50ms

4. Schedule Bandwidth-Heavy Tasks

  • Set backups/updates to run after business hours
  • Use time-based QoS policies (strict limits 9-5)

5. Upgrade Choke Points

  • Replace 10/100Mbps switches with Gigabit
  • Upgrade overloaded routers (check CPU usage)

When to Suspect ISP Congestion?

βœ” Problems occur only during peak hours (7-10PM)

βœ” Speed tests show full bandwidth when alone

βœ” Traceroute shows loss at ISP handoff

Solution: Report to ISP with traceroute data, or consider business-class service.

Key Takeaway: The Proactive Approach

    • Solution: Re-mark traffic at network edge
  3. Overlooking Buffer Settings

    • Defaults cause bufferbloat (300ms+ latency)
    • Modern queues: fq_codel or Cake
  4. No Application Visibility

    • Can't prioritize what you can't see
  5. Hardware Limitations

    • Cheap routers drop QoS under load
    • Verify ASIC support for line-rate QoS

The Bottom Line
The Bottom Line

Your network will prioritize traffic, either by your design or by chaos. Taking control means:

  • Classify all applications
  • Mark traffic correctly
  • Police bandwidth abuse
  • Monitor 24/7
  • Iterate as needs change

Key Takeaway: Your Network Needs Proper Configuration
Key Takeaway: Your Network Needs Proper Configuration

βœ… Audit current QoS settings (most are misconfigured)

βœ… Baseline application performance

βœ… Implement at least basic prioritization today

The Ultimate Factor in Network Performance (Did You Spot It?)
The Ultimate Factor in Network Performance (Did You Spot It?)

Every one of these factors affecting the performance of a network has something in common…

You've seen us talk about bandwidth hogs, latency spikes, and WiFi woes - but what ties them all together?

You can't fix what you can't see.

We've watched too many IT teams play guessing games with their networks because they lacked proper visibility.

Remember when we covered:

  1. That mysterious 3 PM latency spike? (Need monitoring to catch it)
  2. The VoIP calls that only failed during backups? (Need monitoring to prove it)
  3. The "perfect" QoS policy that wasn't working? (Need monitoring to verify it)

This isn't just about having a tool - it's about having the right tool that:
This isn't just about having a tool - it's about having the right tool that:

βœ” Tests continuously - not just when you remember to check

βœ” Shows real user experience - not just device uptime

βœ” Pinpoints exactly where issues occur - not just "something's wrong"
