What is your rig/desktop?

Is anyone achieving significant audio latency gains or xrun stability using a RT kernel

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.
I hear you... I look briefly thru those to look for snares such as irq piling. The
bios in this old Vaio is about a useful as a chocolate teapot! But I set CPU to
performance in user spc (I think...) nowhere to deal with hyper. I don't think this
dual core has it actually.
The second thing to remember is that multicore CPUs
have changed the way lowlatency can ....
Could I trouble you to elaborate on last paragraph a little??
Thnks all for sharing!
