interesting.  but I'd be surprised if any of this was due to the distro,
rather than the kernel.  I normally prefer to run an up-to-date kernel.org
kernel on as many servers as I can, rather than random distro-hacked stuff.

upgrading the rhel server to a kernel.org kernel would be minimal work,
probably...

s/paritition/device/ I hope.  I think journaling to a partition on a 
device that's also being used by the FS in question is no different 
from leaving the journal embedded.  journaling to a device with no 
competing activity appears to be a major win...
