I didn't get any freezes with ext3 and all my audio work (jack, Pd,
MusE).

It still is ext2 somehow, because you can mount ext3 filesystems as
ext2 as well. But you can reconvert, I think.

This seems to change as ext3 evolves. There was a time when it was
faster, currently it seems worse than reiserfs. But I have a lot of
trust in ext3 and I hate having to wait for minutes on e2fsck clean up
after a crash, so I will keep running ext3 instead of reiser or ext2.
I didn't benchmark it, but maybe you can find some on the net.
