I think the current Ubuntu, the 9.10, is indeed performing well, I
installed for a friend recently. But Ubuntu had some problems since
8.04, in 8.10 midi was not working well and 9.04 gave graphics problems
with Intel chips.
The only distribution that ever wowed me was 64Studio with incredible
performance out of the box. But I left it because it became to outdated
for me, I needed more current libraries to program with etc.
Cheers,
Malte
