You may have told us already, but can you tell me the full
configuration of your benchmark machine?  (i.e., how many CPU's, how
much memory, etc.)  Also, what are the current mount options you are
currently using?  And have you redone the ext3 benchmark number with
barriers enabled?  Or was that the original number done with default
mount options that leave barriers disabled?

Thanks!!
