The directory structure may or may not be cached already: these files are in a separate directory from everything else Firefox needs at startup. If your HDD has a seek time of 3-4ms on average, that means it needs to rotate completely in at

If you have a user CSS, the "keep it working" pref has already been set for you, as of Firefox 68. So everything will keep working as it has.

by bzbarsky 7y ago
Not just that, but in an earlier release code was shipped to set the pref for users who already had the file, so that anyone who already had one of these files would not observe any behavior regressions. And yes, file I/O was the issue

The technical answer to the question you asked is "10-20ms, if you're not on an SSD". That's not great, actually, if you're trying to shave tens of milliseconds at a time off startup performance. For what it's

Based on my experience as a Firefox developer investigating memory usage reports, the worst-performing "normal" web pages in terms of memory have: 1) Lots of script (megabytes). 2) Possibly loaded multiple times (e.g. in multiple

The browser _does_ do that. The hard part is detecting "the system is out of memory". Some OSes notify you when that happens, and Firefox listens to those notifications and will flush caches. Some OSes will at least fail malloc
