As far as performance goes, I can only say that my max load is slightly
lower on the 2.4 box then on the 2.2 boxes. Our average load for yesterday
on 2.4 was .23, with a max of 1.11. In comparison, my averages for the
other machines are .27, .27, .23, and .23. The maxes are 1.85, 1.33, 2.06,
1.47.
As far as speed goes, I am not able to measure any real difference (only
testing pop3) between 2.2 and 2.4. I would blame this on the NAS device, a
NetApp Filer F760 being only able to push about 110mbit sustained on the
gig-e network.
Thanks,
Josh
