First of all, you mentioned in another post that you
use x11perf to
create X11 stress. Are there also problems with real world apps?
"Real world" apps work properly (except for the Gnome theme manager
which displays garbage). I only find video performance using Linux a lot
lower than using any of the Mac OS's.
Also keep in mind that neither the vanilla 2.4 kernel
nor the X server
were designed for low latency. Have you tried the low latency and/or
O(1) scheduler kernel patches, and not running the X server with
negative nice values if you are?
Both of those patches (A. Morton and R. Love's ones) were applied to my
kernel. I don't know about running the X server with different nice
values, which advantage would I get? (I am using gdm as my X session
manager).
Last but possibly not least of all, the dmasound
driver has been less
prone to dropouts in my experience than the ALSA driver.
I should try with pure OSS. Let's not forget that the latency test suite
is using the OSS compatibility layer of ALSA.
Thanks a lot. Any feedback is still very useful.
