I did some more tests.  This time running the requests from one 720, and
making requests to another 720.  Here's the results.  Time is in seconds.
The program is figuring tax for the values specified.  I did not restart the
instance before each run, so any new jobs started were there for the next
run.

If someone has an IIS web server that I can hit with my test, let me know
and I'll do the same test.  I just need a URL and a query string data (or
post data).

10 requests
Min: 0.811
Max: 4.207
Avg: 2.398

50 requests
Min: 1.502      
Max: 4.789
Avg: 2.940

100 requests
Min: 0.339
Max: 5.861
Avg: 2.450

300 requests
Min: 0.121
Max: 6.746
Avg: 2.293

Don't ask me why it seems to get better the more it's getting hit (average
time).  Maybe it likes punishement, or maybe it's because of the extra jobs
that were started.  No more than 21 CGI jobs were running at the end of the
test.  

Both machines are being used, but not heavily at all.
