Is anyone achieving significant audio latency gains or

If so, which kernel / where /do I gotta roll my own?
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.
