On my Linux desktop, my soon-to-be-attached testcase scrolls *much* slower when I force-enable layers acceleration.
STEPS TO REPRODUCE:
1. Add the following bookmarklet to bookmarks toolbar
(minor tweak on roc's from bug 579260)...
javascript:void((function(){var%20i=0;var%20start=Date.now();function%20f(){if(++i==50){alert((Date.now()-start)+"ms");return;}document.getElementsByTagName('iframe')[0].contentWindow.scrollTo(0,i*5);setTimeout(f,10);}f();})())
2. Open testcase; wait for it to start autoplaying.
3. Click bookmarklet. (let it scroll & alert() its results)
With layers disabled, I get results around 500ms-950ms
With layers enabled, I get results around 55000ms
(That's a 50x - 100x increase.)
Some of this may be explained by X.org inefficiencies and/or silly GL drivers, but I'm hoping there's something we can do on our side to ameliorate this...

FWIW: on my laptop (with a setup as described in comment 3 except that the card is an NVIDIA NVS 3100M), I immediately hit the crash from bug 629265 upon loading the testcase. No crash on my desktop, though - just slooow scrolling.

On my mac mini running OS X 10.6 (with layers accel defaulted to being on in nightlies), there doesn't seem to be a significant difference for this bug's testcase, for layers acceleration being enabled vs. disabled -- both seem to yield results ranging between 1600ms-2800ms.
So this bug's testcase appears to hit a Linux-specific issue.

For me it is the same. But when I opened Bug 655017 it was ~4x faster.
