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. "Your mileage may vary"
