Take a look at this and you will probably notice
what is going on:

> ab -k -c 900 -n 90000 http://amaterasu/test.php
> Complete requests: 90000
> Failed requests: 5754

> Complete requests: 90000

The robots.txt via SSL test shows 89708 of 90000
Keep-Alive requests, which means the same SSL
connection was reused 99.67 % of the time, which
is why you got such good test results.

But the test.php via SSL test shows 0 out of 9000
Keep-Alive requests, which means that a new SSL
connection was established for each and every
successful request. Considering how CPU intensive
SSL is, your test results are really not that bad.
