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
