Hey Massy! difficut question, asked loads of times with always revised answers. I think there are howto's on the subject by the dozent. I always just get a vanilla kernel from kernel.org and compile it myself, just using the built-in lowlatency features, tailor it completely to my system. It takes some time, but in the end it has always been worth it. I'm running on a 1.8 gHz processor with 1G of RAM, do Nama, Fluidsynth, LinuxSampler, Aeolus, Bristol and LADSPA effects and mostly have no problem with about 10-15 tracks. Of course I apply the effects, when I'm done recording. But in some special cases I had to a pply an effect in realtime, since it was so vital to the sound and playing technique and I didn't die. :-) Then of course there are a lot of kernel packages. There's the -rt series for Debian systems. Don't mix it up with -rt patches, since there's a difference. Don't ask me, since I don't use them. But I've heard they're good, if the chap still does them and hasn't given up out of pure frustration, that he got loads of stupid questions from people, who didn't listen to him or read his comments about not mixing those up. :-) NOTE: If you build your own kernel, make sure that the standard kernel is the default entry in your booloader and stays there, until you're 100%!!! satisfied with it.
