I've been trying to build a chart, but I haven't gotten a lot of
hard numbers yet. Best numbers so far are from Greg Titus at

I actually suspect that you can get better numbers then 250TPM for
the server that Apple is selling with MacOS server, since it has a
RAID array and a pretty fast processor. Greg said that he was doing
500 TPM on a pentium 2 400, but that application could cache all of
its pages once they'd been generated once.
You can get pricing from Sun: 5E's are 6-8, High Ends 20K-100K.
What would really be interesting would be to see how Oracle or some
other database scales as well, since if you're using EOF, you may be
throttled by Oracle more then WO. Not only that, but at some point,
you have to buy 2-3 of everything so that you can have rudunancy,
24/7 operation, fail-over and all that good stuff.
It would also be interesting to find out when its worth moving the
database server to a seperate machine.
