	Definitely!

	Yup.

	I don't know if that will help.  I put it on the desktop and start as
root.  No terminal.

	I never noticed a difference due to qjackctl.

	Nope.  It actually runs better with acceleration - at least on my
system.

	That may help but try killing autorun, syslogd, crond, and other
services first.  I always kill syslogd while recording since every once
in a while it wants to write to disk and I'm not too concerned about
what it's doing while I'm recording.  I restart them after I'm done
(start and stop scripts in qjackctl).
