- Apple Silicon Mac developers who want a Code-OSS editor
- Worth noticing
- The benchmarks use 30 alternating warm-cache launches per app and distinguish fresh-profile results from a separate established-profile run.
Field notes
The page compares Lean v0.4.0 with a same-revision Code-OSS source build on an Apple M3 Max, using medians and p95 timings across several local workflows. Its fresh-profile tests use 30 alternating warm-cache launches per app; a separate profile-reuse run reports a much smaller opening-time difference. The measurements cover task completion and verified outputs, not every visible interaction: the page explicitly excludes physical display paint and says it makes no lower-memory claim.
