We're not talking about Linux threads or apache threaded MPMs in
general here.  The issue is Perl threads.  They are implemented in a
way that makes them slower and heavier than a prefork model in most
cases, due to duplication without copy-on-write benefits.  This has
been pretty thoroughly covered before so please check the mailing
archives if you want more information.

For static content, the worker MPM seems to work very well.  I expect
it would be a good choice for your reverse proxy server.
