Currently Firefox gets about 12-14 FPS in IE 9 Browser hunt Benchmark, while IE9 on the same system gets around 40+ FPS.

2D graphics performance on Windows 7 => possibly Direct2D related => CC Bas

As far as I can see Canvas2D is unrelated. It looks to be SVG, haven't looked into this yet though.

Let's call this a Graphics bug then.

Have you tried profiling, instead of guessing? Is this even graphics-bound?

I haven't done anything, I admit. OK, back to Canvas 2D.

Indeed, this has nothing to do with canvas, though it's a tossup whether it should be in SVG or Graphics. Here's a profile: https://spreadsheets.google.com/ccc?key=0Asl0BZnEZ615dFBaUG55WElxNGJVbFhySm9waTh2dEE&hl=en&authkey=CJrpt-IG#gid=0 Looks like we're hitting some slow/fallback paths, including things like unpremultiplying image alpha in a number of cases.

(In reply to comment #4) > Have you tried profiling, instead of guessing? Is this even graphics-bound? I realize my comment was a bit vague. What I meant by Canvas2D being unrelated was that the benchmark doesn't do anything Canvas, but only SVG. I didn't mean to suggest that's where the performance bottleneck was.

I am still seeing about 12 fps with the current Nightly, even in full-screen mode.

Well, getting a little better, I was around 17-19 FPS tonight, but still dreadfully slow.

Here are my results: * Fx 8 or Nightly 11.0a1/20111203: 7 FPS * IE 9: 27 FPS Adapter Description: Mobile Intel(R) 4 Series Express Chipset Family Vendor ID: 8086 Device ID: 2a42 Adapter RAM: Unknown Adapter Drivers: igdumd64 igd10umd64 igdumdx32 igd10umd32 Driver Version: 8.15.10.2555 Driver Date: 10-13-2011 Direct2D Enabled: true DirectWrite Enabled: true (6.1.7601.17563) ClearType Parameters: Gamma: 2200 Pixel Structure: RGB ClearType Level: 100 Enhanced Contrast: 100 WebGL Renderer: Google Inc. -- ANGLE (Mobile Intel(R) 4 Series Express Chipset Family) -- OpenGL ES 2.0 (ANGLE 0.0.0.885) GPU Accelerated Windows: 1/1 Direct3D 10 AzureBackend: direct2d

Windows 7 with HWA For me, Nightly 27 and IE 10 both get around 33 fps while Chrome only hits 29 fps. But Firefox has no sound, while IE and Chrome have.

I get 40-50 fps with recent Release (25) and with MSIE 11 ~30fps. Can we close this?

I just ran this on Nightly on Mac 10.9, and Firefox maxed out at 13FPS. I'll check on windows later on.

Windows Results: Firefox 25, 45-48 FPS Firefox nightly 4 FPS (We regressed in nightly) IE 11 31 FPS So release is good, but nightly has regressed significantly.

Tyler, are you up for finding a regression range here?

So I was going to see if bug 934860 lead to the regression here, but in fact I found the opposite (sort of): In the 2013-11-06 Nightly, this demo is unbearably slow - less than 1fps, nearly hanging the browser. In the 2013-11-07 Nightly, I get about 20-22fps, which matches current Nightly. So something in that range significantly increased the performance, though not to anything spectacularly fast.

Looks like this regressed in the 2013-10-18 Nightly (steady 60fps before, <1fps after), giving a regression range of https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=423b9c30c73d&tochange=4e7d1e2c93a6 and was partially fixed in the 2013-11-07 Nightly (<1fps before, 21fps after).

Further narrowed down on inbound. Last good: https://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-inbound-win32/1382003536/ First bad: https://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-inbound-win32/1382004254/ Regression range: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=9c8ab7e9ae41&tochange=45d9e6cd3473 So either bug 926706 or bug 923193.

Regressed by a417424f9213 Robert O'Callahan — Bug 923193. Make transform-origin on SVG elements use the SVG bbox as the reference rectangle. r=heycam And backed out it in m-i today. 3fb151446ec5 Robert O'Callahan — Backout changesets 37f9a5424227, c1578a4fc86d and a417424f9213 (for bugs 933354, 929021 and 923193 respectively) while we figure out performance regressions 4a5c39f4cf22 Robert O'Callahan — Backout changesets 238b3c81f42c and rest of a417424f9213 (bug 928798 and rest of bug 923193 respectively)

923193 is backed out. We'll re-check this before relanding.

Umm, but even with Bug 923193 backed out there still remains another Regression of >10fps on Release/Beta (as stated above >40fps) vs. Aurora/Trunk (~30fps).

Maybe it's bug 935008 (i.e. bug 922942)?
