Recommended Network Performance Metrics

Network Item

Definition

Recommendation

Bandwidth

The maximum rate at which data can be transferred over a network connection.

  • Home networks: 100 Mbps (Megabits per second) or higher

  • Business or enterprise networks: 1 Gbps or more

Latency (Ping)

The time it takes for a data packet to travel from the source to the destination and back is usually measured in milliseconds (ms).

Low latency is crucial for real-time applications.

  • Less than 20 ms is excellent

  • 20-50 ms is good

  • 50-100 ms is acceptable for most uses

  • Anything above 100 ms can start to affect performance, especially in gaming.

Jitter

The variation in latency over time, which can affect the consistency of the network connection.

  • Low jitter is important for smooth performance. Less than 5 ms is excellent, 5-20 ms is acceptable, and anything above 20 ms can cause noticeable issues.

Packet Loss

The percentage of data packets that are lost during transmission.

  • Ideally, packet loss should be 0%.

  • A loss of less than 1% is generally acceptable for most applications.

Throughput

The actual rate at which data is successfully transferred over the network can be affected by network congestion and other factors.

  • Throughput close to or matching the bandwidth capacity is ideal.

    • For example, if your plan is 100 Mbps, achieving throughput close to that value is good.

Error Rate

The rate at which errors occur during data transmission.

  • Low error rates are essential for reliable performance. Ideally, error rates should be minimal.

Network Utilization

The percentage of the available bandwidth that is actually being used.

  • Moderate utilization (50-80%) indicates efficient use of available bandwidth without overwhelming the network.

  • High utilization (above 90%) can lead to congestion and slower performance.

Connection Stability

How consistent and reliable the network connection is over time.

  • A stable connection has minimal fluctuations in performance and uptime.

You can use these tools to check your network’s metrics:

  • Speed Test: Websites and apps like Ookla’s Speedtest or netspeed_icon1.png Internet Speed Test can measure bandwidth, latency, and sometimes jitter.

  • Ping Test: Command-line tools (e.g., ping in Windows or Unix-based systems) can measure latency.

  • Traceroute: Shows the path data takes and can help identify latency or routing issues.

  • Network Analyzers: Tools like Wireshark can provide detailed insights into network traffic, errors, and performance issues.
