The Bugbug bot thinks this bug should belong to the 'DevTools::Netmonitor' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

the regressor was backed out, I'll close this (we should be careful when trying to re-land the patch to check if there are still performance issues)
