"The Apache/Perl integration project brings together the full power of the Perl programming language and the Apache HTTP server.
With mod_perl it is possible to write Apache modules entirely in Perl. In addition, the persistent interpreter embedded in the server avoids the overhead of starting an external interpreter and the penalty of Perl start-up time."
mod_perl 2.0
Anybody out there using mod_perl 2.0 yet? Apache 2.0 seems to be getting more and more common in the wild, but mod_perl 2.0 is taking a while to become adopted. I've tried porting a couple of my old modules to it, but didn't find the online documentation complete enough. That said, Apache/mod_perl 2.0 is yet another powerful combination. --Wim
Have been playing around with Apache2 and mod_perl a bit. I really like the input/output filters. Now in combination with XSL some really cool potential. --fozbaca
Debian's mod_perl packages
I'ved finally moved from a custom Apache/mod_perl compile to Debian's packages. I must say, it's working quite well. Everything running through the webserver is running faster, including Apache::MiniWiki and Apache::TTF. --Wim
Tuning mod_perl
I've been trying to profile the slow pieces of Apache::MiniWiki, but haven't been too succesful in getting meaningful debugger profiles. Apache::SmallProf doesn't work as expected, Apache::Status isn't detailed enough, Apache::DProf won't give summary info on child routines (only the main mod_perl handler)... Here's a fairly decent set of tips though:
