Had a chance to do some big javascript refactoring at work, and something I noticed was the amount of timers on a single script of ours (over 10 setInterval() calls).

We found a significant performance gain, ~10% faster load time for that particular script: gist.github.com/webdevinci/aeb7e568c3e3cbe0d89eb2…
