Hi,
could there be any disadvantages for averaged desktop users, server
usage etc., if the kernel 2.6.39 is build as PREEMPT kernel?
Today I installed the kernel from the repositories of a major Distro:
$ uname -a
Linux debian 2.6.39-2-amd64 #1 SMP Wed Jun 8 11:01:04 UTC 2011 x86_64
GNU/Linux
Some time ago I build the kernel myself:
$ uname -a
Linux debian 2.6.39.1 #1 SMP PREEMPT Tue Jun 7 01:40:05 CEST 2011 x86_64
GNU/Linux
I'm asking, because I want to know, if it would be reasonable to appeal,
that major distros should build it as PREEMPT kernel.
Regards,
Ralf

Hi Ralf,
My understanding that there would probably be not much differences for desktop
users. However (most) server users would not want a pre-emptively built as they
generally require to share their services whereas pre-emption can cause delays on
some services...
FWIW - this is only my limited understanding.. I have a pre-emptive kernel on my
general purpose laptop.. On my home server I have no latency on low value kernel
timer.. .
I recommend either building your own kernel (fairly easy, especially if you save
your config from previous builds).. Or getting a pre-built audio purpose kernel..
cheers
