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

Allan
