nothing vs Registry vs module

[Matthew <ma...@matthewboehm.com>]

Firstly, real world comparison between no mod_perl and using Registry: 
Simple cgi, using Apache::DBI and CGI and HTML::Template. Loading 1 
template file and doing about 30 template param replacements.

Using "ab" to do 500 requests at 2 concurrents took about 47 seconds. 
Simply adding ModPerl::Registry to that directory and rebooting web 
server, results down to 2.3 seconds!  Amazing.

Secondly, seeing such a speed increase above makes me wonder the big 
differences between ModPerl::Registry and a handler module. Am I going 
to see an even more significant speed increase doing as a module?

Thanks,
Matthew

while these results are quite old, the relative differences should be
pretty much the same

The vast majority of the speedup is in the compilation / interpreter 
loadtime.  You will not see a another 20x increase in speed switching to a 
handler module.  I bemoan the fact that some of our shared hosting servers 
run Perl and PHP via suexec for EVERY call.  Ouch!
