20205 models compared, **0 improved, 6 regressions**, performance 4 improved, 1 regressions.
| Phase | `wasm-jit` | `pr/17175` | Change | Change, same phase |
| --- | --- | --- | --- | --- |
| frontend | 1:15:27 | 1:15:47 | +0.4% | +0.5% |
| backend | 1:49:48 | 1:49:44 | -0.0% | -0.0% |

| total | 19:27:31 | 19:17:59 | -0.8% | -0.9% |
Time spent on the 20205 models both runs have. The last column counts only the 20199 that reached the same phase in both: a model that fails earlier stops paying for the phases it no longer reaches.

Caveats
- 1 libraries of the baseline run were not tested by the pull request run: Buildings_11.
- The baseline is the newest run of wasm-jit, not the commit the pull request is based on, so a difference can also come from something merged into wasm-jit since the pull request was branched.
