Would love to see how Safari handles your benchmark! I find it pretty fast, but maybe that's just bias because it treats my battery nice.

I ran three trials of each on a min spec 2019 MacBook Pro 16". All numbers are ms rounded to the nearest integer, all browsers are latest stable. I also loaded the page with dev tools closed since that affected times.

Browser: (trial 1 prep, trial 1 chart), (trial 2 prep, trial 2 chart), (trial 3 prep, trial 3 chart)

Chrome: (649, 347), (638, 343), (618, 358)

Firefox: (353, 307), (358, 307), (361, 308)

Safari: (281, 264), (287, 258), (309, 262)

Similar experience. Beating WebKit on macOS in rendering performance or energy use is very hard for both Chrome and Firefox (and the clones).

Very interesting. Thanks a lot! Firefox did really well, that’s cool to see.

there's an artificial 500ms delay in there between fake data gen and chart drawing so it's easier for me to isolate the two in the perf timeline :)

i don't have access to a Mac, so you won't get this from me!

Fair enough! Thanks anyway, though.
