GitLab lags behind GitHub on various performance metrics, particularly on visual performance metrics.
For example, comparing https://github.com/gnachman/iTerm2/tree/master/tools to https://gitlab.com/gnachman/iterm2/-/tree/master/tools, differences in FirstVisualChange are fairly small (16%), but these stretch out with additional changes, with fullyLoaded being 300% slower.
Overall, the SpeedIndex of the GitHub page is 854 and the GitLab page is 1679.
| GitHub | GitLab | Difference | |
|---|---|---|---|
| FirstVisualChange | 833 | 967 | 16.09% |
| LastVisualChange | 1076 | 4375 | 306.60% |
| PerceptualSpeedIndex | 839 | 1346 | 60.43% |
| SpeedIndex | 854 | 1679 | 96.60% |
| VisualComplete85 | 833 | 2117 | 154.14% |
| fullyLoaded | 1216 | 3925 | 222.78% |
