Vite vs esbuild vs tsup
Tick the candidates you care about and the charts, winners and table redraw for just them: same run, same rig, same samples. Winners come from the numbers alone; the story is in the post.
Tests
Test 1 Time per pass
20 measured passes over the corpus. Box is the middle half of the runs, line is the median, whiskers reach the fastest and slowest pass, dots are every run. (LOWER ms = FASTER)
