[gentoo-user] Adobe-flash becomes quite slow.

Adobe-flash becomes quite slow in my laptop after I updated world(or maybe I
reconfigured kernel options) several days ago. I've made a lot of
modifications, so I'm not sure exactly which action leads to the malfunction
of adobe-flash.

I use the latest stable version of adobe-flash(10.2.153.1),
nvidia(260.19.36).

What you guys know what factors are affecting the performance of
adobe-flash?

Here's the recent main modifications to my system:
1. (/etc/make.conf) change CFLAGS and CXXFLAGS from "-O2 -march=i686 -pipe"
to "-O2 -march=native -fomit-frame-pointer -pipe"
2. change the *Preemption Model" in the kernel config from "Voluntary Kernel
Preemption" to "Preemptible Kernel"
3. excluded SMT scheduler support in the kernel config(my CPU doesn't
support hyper-threading)
4. I tried the latest 2.6.38 gentoo-sources, and roll back to 2.6.36-r8

Thanks in advance :)

[note: I replied back to the list (which appears to be misconfigured today,
"reply" sends to the original sender instead of the list as normal).]

Have you rebuilt your nvidia card's x11 drivers?

adobe flash is just slow with composite. And its performance differs greatly 
between minor versions.

I use strace to trace syscalls of
`/opt/Adobe/flash-player/libflashplayer.so` and found many errors like this:

Any ideas?

Thanks in advance :)
