So, you've benchmarked Hello World. Why do you care?

I've worked on a lot of large scale Catalyst applications, and done a
fair amount of optimisation work, and I have *never* found Catalyst to
be the bottleneck in my performance testing. Better still, because
the teams had used Catalyst they had more time at the end of the
project for performance testing and optimisation and it was easier
to clean up the code because the architecture of the application was
flexible. That really, massively beats caring about how fast Hello
World is :)

I'd point out that BBC iPlayer is built on Catalyst and DBIx::Class
- are you going to tell me you're going to need to scale further than
they do? :)

Catalyst is threadsafe. Your DBD:: may not be, or something else you
load. But FastCGI is a much better production environment than mod_perl
anyway.
