Funny enough on my machine, Chrome is the slowest on https://browserbench.org/Speedometer2.1/

401 - Chrome

446 - Firefox

546 - Safari

357 - Chrome with extensions

511 - Chrome without any extensions

433 - Clean firefox install

500 - Clean edge install

On an AMD Ryzen 7950X3D / 5600MHz RAM

Interestingly, I got substantially different results depending on whether I used chrome with my typical extensions or not. Looking at the flamegraph, I don't seem to see the full picture of why there's such a substantial difference. Bitwarden/React Developer tools (the 2 primary extensions I use) don't seem to make enough of an impact to account for the roughly 40% performance increase seen without them. The browserbench javascript accounted for ~38.6% of the overall time taken for the benchmark, but the sum of my extensions was only 6.5%. I'm not incredibly familiar with browser performance profiling, so there's probably more to the story.

Probably subjective to your particular set up - I just got the opposite results on my mac:

202 ± 4.7 - Chrome

184 ± 5.0 - Firefox

171 ± 2.6 - Safari

fyi, if you're uncertain in the single-digits place, you have no precision in the tenths place. for experimental uncertainty, it's always one sigfig

Neat site but it almost needs a flash/epilepsy warning =P

Isn't that pretty much irrelevant? Won't network speed etc make much more of a difference?
