One correction -- the IBM x335 has 2GHz Xeons, NOT 3GHz!

> o Install on a NEW Sunfire X2200 server (dual Athlon CPUs) running Solaris 10
> o Install on same X2200 running RHEL 5

> We did some very basic tests. We installed RT 3.6.4 on the V440 (also Solaris 10)

> o The X2200 running Solaris was marginally faster than our existing machine
> o The X2200 running RHEL 5 was about three times faster than our existing machine
