[Bug 144216] Re: Slow switching tab in firefox/opera when the desktop effects are enabled in Gutsy Gibbon

[jrepp]

I'm running patched up 7.10 on a dell inspiron 1720 (nvidia 8600 gtm).
I'm using the non-free nvidia drivers installed via the restricted
driver manager. Also, I am running compiz + emerald.

Running just firefox 2.0.0.13 I profiled switching between three tabs
two times and have included my results below. You can see that most of
the time is spent in the nvidia driver. I'm not sure which calls are
being made but I will try and do some more investigation.

CPU: Core 2, speed 2001 MHz (estimated)
Counted CPU_CLK_UNHALTED events (Clock cycles when not halted) with a unit mask of 0x00 (Unhalted core cycles) count 100000
CPU_CLK_UNHALT...|
