On Linux Ubuntu 8.1 and on a Quad-Core single CPU machine (CPU speed does not make the difference), my tests show that Cherokee is faster (both with and without keep-alives) than Accoria Rock (closed-source).

I could not realize this before simply because I was not able to run Cherokee.

See:
http://gwan.ch/   (for Rock)
and
http://gwan.ch/en_timeline.html#cherokee

I don't know if Cherokee would beat Rock on the Spec
test (see spec.org) but this is nevertheless good news!
