nothing vs Registry vs module

[Matthew]

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
