Check that your CPU speed is not getting screwed up by the power management (i.e. you have the full 650 MHz). I don't know if it's even a problem for Dell laptops, but it was/is for certain Thinkpads. > I notice that running Ardour (Beta .9beta 9 RPM from Thacs RPMs), after > I have fired up Jackstart or Jackd-realtime from Qjackctl with -d alsa > hw:0 1024 2 as root and then fire up Ardour and add a track, the pcm > chain is connected (also visible in Qjackctl "Connect")and I have sound > but the pc starts running slow and the Hard drive light is constantly > on.

I have a Thinkpad with similar specs, and I found upgrading from 128 to 384 Mb RAM made a huge difference in performance. Make sure you get the right kind, or at least a compatible kind. It seems likely that this is the problem; even if it isn't, it's still a very worthwhile (and cheap) upgrade. Cheers, Chris
