"In [this] series of articles we are going to talk about mod_perl performance issues. We will try to look at as many aspects of the mod_perl driven service as possible. Hardware, software, Perl coding and finally the mod_perl specific aspects...."

"If you are building a fan site and you want to amaze your friends with a mod_perl guest book, any old 486 machine could do it. If you are in a serious business, it is very important to build a scalable server. If your service is successful and becomes popular, the traffic could double every few days, and you should be ready to add more resources to keep up with the demand. While we can define the webserver scalability more precisely, the important thing is to make sure that you can add more power to your webserver(s) without investing much additional money in software development (you will need a little software effort to connect your servers, if you add more of them). This means that you should choose hardware and OSs that can talk to other machines and become a part of a cluster."

"On the other hand if you prepare for a lot of traffic and buy a monster to do the work for you, what happens if your service doesn't prove to be as successful as you thought it would be? Then you've spent too much money, and meanwhile faster processors and other hardware components have been released, so you lose."
