Like the other responses, I don't think it's the CPU per se.
Some things to look into if, like me, you're still using "old" EIDE /
* use a dedicated drive for audio
* put the audio drive on a separate physical cable & channel than
the system drive (this made a big difference for me; I used to
have my main drive on /dev/hda and audio as a slave on /dev/hdb,
but I get much better results with audio being on /dev/hdc)
* use hdparm to select the highest dma setting your audio drive
supports. (hdparm -I /dev/hd* will tell you all the detected
capabilities and their current settings).
With this setup, I've gone as high as 19 mono and 2 stereo tracks. I
don't know how high I could go; that's the most complex session I've
done to date.
