initiating SRU process. ** Description changed:
Browsing with Firefox 3.0b5 on Hardy (All updates applied) causes Xorg to use 50-60% CPU all the time. This is not limited to a particular site or page - it happens any time when Firefox is rendering pages. The high CPU usage makes browsing very jerky - switching tabs takes more time than it should, pages appear frozen for a brief moment. + + === + From https://bugzilla.mozilla.org/show_bug.cgi?id=430530#c4: + + After some testing, it looks like this gets pretty bad on linux. + + Once we hit sqlite's cache size, sqlite starts hitting the disk pretty hard. + While the database is small this isn't a big deal (we don't hit the cache + limit), and once we're up-to-date it isn't as bad (we aren't adding as much + data). + + But during the middle/end of the push to get the complete database, things take + way too long, and we're thrashing the disk the whole time. + + We can reduce the amount of IO by increasing the cache size, and that'll help + some (it'll help a whole lot if we increase the cache size by enough to hold + the db). We might also need to look at throttling the update process a bit, so + that we don't slam the system all at once... -- [MASTER] Committing to urlclassifier3.sqlite causes excessive CPU usage and disk I/O https://bugs.launchpad.net/bugs/215728 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
