for speed: set the blocksize=system pagesize, 4k on intel. -b 4096
On filesystems that will just have big files on them, you can reduce the
number of inodes aswell, to reclaim disk space. Eg on the oracle DB fs you
could probably go mad and use 64kB/inode.
also, do you know what sort of a stripe/chunk size your raid controller
uses? if you do, you can give mke2fs a hint to optimise the fs for that
-R stride=<blocks per stripe>
eg fs with 4kB blocks, and a 64kb raid stripe, would be

shouldn't be with 2.2.14, which has large memory support merged in iirc.

there might be some useful info on: http://linuxperf.nl.linux.org/
