There was a problem hiding this comment.
I have not been following these changes closely enough to have an informed perspective on the potential broader implications here, but in isolation this makes sense to me as a targeted performance tweak

Follow-up from #72522. My estimates were off, and a parallelism of 15 made Safari the slowest test suite despite us now having a bit of headroom for saucelabs concurrency. Safari took 40 minutes to run in the first DTT with Device Farm, while the next slowest test suite (Mobile UI) took 35 minutes.
Increase Safari parallelism from 15 to 20, with the expectation that this will speed it up from about 40 minutes to about 30 minutes.
