Experimental Results
Experimental Results
These measurements come from the upstream project, which compared speedtest-go with speedtest.net and sivel/speedtest-cli using an earlier version.
Summary
| Finding | Detail |
|---|---|
| Testing time | About half as long as speedtest.net, and shorter than speedtest-cli |
| Accuracy | Closer to speedtest.net than speedtest-cli is |
Distances group the servers by how far away they are:
| Distance (km) | Meaning |
|---|---|
| 0 to 1000 | Domestic |
| 1000 to 8000 | The same region |
| 8000 to 20000 | Very far. 20000 km is half the circumference of the Earth |

| 1000 to 8000 | 58.02 | 54.74 | 26.78 |
| 8000 to 20000 | 6.94 | 8.32 | 2.58 |
Average testing time (seconds)
| Distance (km) | speedtest.net | speedtest-go | speedtest-cli |
|---|---|---|---|
| 0 to 1000 | 45.03 | 22.84 | 24.46 |
| 1000 to 8000 | 44.89 | 24.45 | 28.52 |
| 8000 to 20000 | 49.64 | 34.08 | 41.26 |
The bold value in each row is the one closest to speedtest.net’s, or the shortest time.
Method
- 9 servers were chosen at random, 3 in each distance group.
- Each tool tested each server twice.
- The order of the tools alternated between servers, so no tool always ran first.
