To be honest, I don't know how I could see a difference. I am running 
lowlatency right now and see no xruns at all with .6ms latency no matter 
how much I have running. Concidering the audio card has a 1ms latency to 
add to that... There is nothing to gain by going lower.

To be honest, hardware, bios and system settings have more to do with 
things than the kernel. For example, I do not think a RT kernel will make 
any difference to a machine running hyperthreading or ondemand, both will 
make for higher latencies for stable operation.

The second thing to remember is that multicore CPUs have changed the way 
lowlatency can be achieved.
