Yes, cherrypy.wsgiserver, paste.httpserver, twisted.web2, flup, etc.
At openplans we (well, Luke) did some performance testing, in our case
of an intermediary we're writing. The same basic pattern should fit
this. I wrote a couple WSGI apps for that that showed particular kinds
of behavior. I guess all I really did was an application that
periodically was really slow. Another interesting case would be an
application that yielded content very slowly. Different combinations of
app_iter and start_response writer could be interesting. And of course
the simplest example (which is usually all people do) of a trivial
application that just serves up a single short string. Oh, and I should
do one that serves up a large string, in one chunk and many chunks.
Personally my own interest is in servers that act well even when the
apps act poorly, more than the single case of a fast server with a
perfect and fast application behind it. The perfect app is easy to
test, so it'll be in there too of course, but just one of many.
I think most of the work will be in setting up httperf with some scripts
to invoke it and the other server. The other stuff can already be glued
together quite easily by Paste Deploy. Well, not counting some of the
servers that are harder to put together, like Apache+flup/fastcgi (or
another server there), or mod_python generally. I suppose I'll just
write up some simple httpd.conf's for these cases, and I guess I can
fire it off from a script easily enough. Well, I'll probably look to
someone else to do mod_python (and mod_wsgi before long), since I'm bad
at setting those up. Once Apache+flup is setup, Apache+mod_python would
probably be easy for someone who knows there way around.
