yes, but a WARNING: anyone thinking of moving to 2.3.99pre5 or above:
there appears to be a serious bug that will kill ardour's performance
(as well as Benno's test programs). I've posted a followup on
linux-kernel to the person who first noticed it. Basically, writing a
few hundred MB causes the box to slow to a crawl as memory utilization
goes through the roof. This was not the case in 2.3.51. Right now, I
cannot run Benno's hdtest program (it will never complete), and ardour
cannot record more than a minute or so of a handful of tracks without
a dropout. Again, this appears to be a new bug introduced in 2.3.99
somewhere.
