What this test shows
A normal speed test tells you download and upload speed. Loaded latency looks at what happens to ping while the connection is busy.
Until LinkSpeed adds a fully automated loaded-latency measurement, use this practical test method:
- Run a normal LinkSpeed test and note the ping and jitter.
- Start a large download or cloud backup.
- Run the test again while the connection is busy.
- If ping jumps sharply, you may have bufferbloat.
How to grade the result
| Loaded latency increase | Likely quality | What it feels like |
|---|---|---|
| 0-30 ms | Excellent | Gaming and calls should stay smooth. |
| 30-75 ms | Good | Small delay under load. |
| 75-150 ms | Variable | Noticeable lag during downloads/uploads. |
| 150 ms+ | Poor | Calls, games and remote work may suffer. |
What to fix first
Try Ethernet, reduce background uploads, enable router QoS/SQM if available, and check whether the problem is worse on Wi-Fi than wired.
