Hi,
I am trying to see why a trivial driver reading an ADC on an EP9312 ARM
board has slowed by a factor of three. Since I installed it under 2.6.29
a couple fo years ago.
It's looking like this is due to a kernel update I did in the mean time
to 2.6.32
I have just built a new toolchain and rebuilt the kernel to 2.6.33 and
the result is about the same.
I recall a number of years ago running a 2.6.11 kernel and the system
was incredibily responsive. I could be building kde-libs, downloading at
full speed browsing and listening to mp3 decoded music all without the
slightest lack of responsiveness in the browser not a glitch in the mp3
playback.
It was truly impressive.
Now I find if I am rebuilding the toolchain , the browser or any other
window can take over a second to respond to a redraw ( 2.6.32 on this
machine).
Now I've seen comments on audio forums that there was nothing better
than linux 2.6.11 for real time audio work. I'm wondering whether there
is not a general degradation in the linux kernel as time goes on. It
certainly seems to be getting forever bigger and slower.
Would there be any value in trying to rebuild a 2.6.11 based system for
realtime work ?
TIA,
