Thanks to share your results.

During my tests I found somewhat similar, although I didn't went into
details like you with GlusterFS, I was more interested in tunning my
RAID controller and ext3 filesystem.

Also note - has been reported on the list before - that with the
default, glusterfs-volgen created configuration 'ls -lR' does NOT
re-sync the content between AFR nodes (at least not with CentOS 5.4
x86_64). 'ls -lR'  works without the translators.

Seems for me it's safer and faster to use a stripped down config.
