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.
