I have copied my system onto an ext3 filesystem and ran the same test.
It seems to be much better. These are all the XRUNs from running my
JACK test while untarring a kernel tree in /tmp while doing `find /
-ls'. There are not too many. Previously I had to send excerpts, this
is the entire log. With reiserfs, I was not having to artificially
stress the filesystem at all to produce WAY more XRUN traces than this.
