You didn't mention this in your initial mail: Do you run jackd with 
realtime capabilities? Is your kernel patched for low latency? If not

Alsa drivers reflect -- in the best case -- the hardware's limitations

Before doing that it would make sense to google for "pci latency" and 
read http://myweb.cableone.net/eviltwin69/ALSA_JACK_ARDOUR.html

The recent discussion of lighweight windowmanagers was misleading. If

run KDE, watch flashs and abuse openoffice while ardour is happily 
playing out 20 tracks. Things might be sluggish but there will be no 

btw: Could you try to start new threads for new questions?
