None that I have noticed. Then again, my main fileserver gets something
like 1% load average and 10% mem usage (unless I'm shuffling large files
locally, the gigabit adapter and Samba's buffers eat both up pretty
quickly). Pulling notions out of my ass, I'd guess that larger PE-sizes
are better now than they were before since most disks have larger
buffers, our boxes have more RAM and Moore's law is seldom broken.
Heinz, is this the reasoning behind upping the default PE size or were
there other considerations?
