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. Wow! Pci(e)? USB? Fw? What IZ interface? That's a lot better than I'm getting.

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!
