==== File IO ====
File IO is tested using the tp5 test set in the [[#xperf]] test. ===== Possible regression causes =====
* '''nonmain_startup_fileio opt (with or without e10s) windows7-32''' – {{bug|1274018}} This test seems to consistently report a higher result for mozilla-central compared to Try even for an identical revision due to extension signing checks. In other words, if you are comparing Try and Mozilla-Central you may see a false-positive regression on perfherder.
