Details
Here's a profile of loading cnn.com on Windows and refreshing the page four times, focused on time spent in cycle collection: https://share.firefox.dev/3Q4LuGp
Here's a Chrome profile of doing the same (not focused on anything): https://share.firefox.dev/3tLrAc1
Chrome spends a lot less time in GC-like functions, e.g. cppgc::internal::Sweeper::SweeperImpl::PerformSweepOnMutatorThread
