Alex,
Actually, this is my first try at a production deployment, and I have
not set up another to test against. Is there a standard "ab" test that
is usually run for comparison in web2py community? In any case I ran
the following command with sqlite as the backend server (but doubt it
matters for this page) for the cherokee setup and the web2py builtin:
ab -n 1000 -c 5 url

Sure, I'll make it a slice.
