User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.97 Safari/537.22 Steps to reproduce: I've witnessed a host of SVG rendering slowdowns since upgrading FF16 to FF19 on Windows 7 and OSX with all add-ons disabled. The worst slowdown appears to be due to removing SVG elements. To reproduce this run the attached html. Actual results: On my Win 7 box. The page load times are as follows (1) If you paste the URL into a fresh FF 19 tab: ~4 seconds (2) Hit reload on the FF19 tab: ~20 seconds For reference ... IE 9 new tab: ~2 seconds IE 9 reload tab: ~2 seconds Expected results: In FF 16 pasting the URL into a new tab (1) and hitting reload (2) rendered in the same time. In FF 19 there is a 5x slowdown. This slowdown has also been exhibited in my applications when I am destroying svg elements, etc (i.e. not just while loading a new page). This has negatively affected various situations, such as D3 brushing, with much smaller datasets.
It's not so easy to observe the slowdown, I would say it's pretty reproducible when the user is reloading the tab with the testcase and switching to another tab, Firefox hangs (repeat these steps if need be). A possible regression range, someone needs to confirm: m-c good=2012-10-07 bad=2012-10-08 http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ecd4c4304219&tochange=9738e5a0190a
I got a different regression range. Regression window with STR of Comment#0(reload page(F5)) is as follows: Regression window(m-c) Good: http://hg.mozilla.org/mozilla-central/rev/b274e8e3479f Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/18.0 Firefox/18.0 ID:20120928160219 Bad: http://hg.mozilla.org/mozilla-central/rev/b62b229a4d41 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/18.0 Firefox/18.0 ID:20120928161018 Pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=b274e8e3479f&tochange=b62b229a4d41 Regression window(m-c) Good: http://hg.mozilla.org/integration/mozilla-inbound/rev/9f476b4ac1e1 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/18.0 Firefox/18.0 ID:20120928040137 Bad: http://hg.mozilla.org/integration/mozilla-inbound/rev/6b58397ad735 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/18.0 Firefox/18.0 ID:20120928042236 Pushlog: http://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=9f476b4ac1e1&tochange=6b58397ad735
That range makes more sense, since bug 539356 is a very likely culprit. Probably the issues here are covered by some of the follow-up bugs that have yet to be fixed, most notably bug 827915 and it's sub bugs.
RichH, does the Windows build here fix the issue for you: http://email@example.com/
Depends on: 827915
The try server build does NOT seem to fix the problem ..., I can still reproduce the slowness when reload page.
Thanks for checking; I was just curious.
Can you retest with latest nightly please?

I no longer see the continuous performance decrease running in Nightly! Computational performance in the model and rendering the view is still slower than FF v16.02 but the most serious performance regression appears to be fixed.
