It makes sense though. All the other tools do more setup work on each
request: parsing input, manipulating it into objects, etc.

Hmm... To me that means it's equivalent, not blowing away mod_perl.

The IBM JDK has a JIT, but no Hotspot equivalent. They have the fastest
JVM on x86 though. Check out the scores here:

One thing I discovered when testing Caucho's JSP last year is that they
do a really good job of generating efficient servlets from JSP. I was
not able to write a faster "hello world" servlet than the one they
auto-generated from a JSP page.
By the way, as a cautionary tale on "hello world" tests:
These tests appear to show mod_include handling SSI pages twice as fast
as Apache::SSI. However, in tests we've done with real production pages
(30-60K, half dozen or so includes per page) Apache::SSI was actually a
little bit faster. Of course this was about a year ago so the tables
may have turned since then.
