Jim, My own experience... Waaay back in the days of KDE3 and Firefox 13(?) i could easily have 700 tabs and 300 windows open on a much less capable Linux/amd64 desktop w/o any appreciable slowness. For the past couple years, even with a decent machine and 32GB of ram, i have *massive* latency (upto 30 second tab loads in some cases) in all firefox profiles i run (i generally run 3-5 different profiles simultaneously to do different tasks and split load as too many tabs/windows is glacially slow. In sum i still run 300-1000 total tabs and several hundred windows). My fans spin high because the CPU is under duress... Anyway, while testing FF 53 before deploy to the organization's linux NFS server the other day, i started from a terminal window (rather than the DE Launcher) and saw a bunch of Gtk and Gdk assertion failures and such when hitting a specific page. I've seen these before, but they usually came in small dribbles; now they were just perpetual on that site. I saw references to Adobe Flashplayer being responsible for this, and lo/behold, upon switching Flashplayer to "Never Activate", the Gtk/Gdk messages stopped. I then disabled Flashplayer in all of my other profiles , and my Atlassian Confluence tabs suddenly became usable again. (instead of 30 seconds of grinding waiting to edit a page or authenticate, it took no more than 4-5 seconds). While i'm massively disappointed in the performance still (yeah, partly the freakin' web and it's abundance of dazzle/privacy-theft sites), it turns out that Flashplayer being active for a single tab was killing my system. Fortunately, it seems most websites are now either flash-free, or able to run without it. (i have NoScript installed as well). So, try making sure all your plugins (esp Flash) are disabled and see if you can still replicate the slowness. (or run in 'safe' mode). (i feel so dirty now using the cop-out Mozilla Support "run it in SAFE MODE" excuse :-( ) --stephen _______________________________________________ Enterprise mailing list Enterprise@mozilla.org https://mail.mozilla.org/listinfo/enterprise To unsubscribe from this list, please visit https://mail.mozilla.org/listinfo/enterprise or send an email to enterprise-requ...@mozilla.org with a subject of "unsubscribe"
