For businesses the cost-to-develop and cost-to-maintain are usually more important than handler performance. The reason is that in most medium-large transactional web systems the bottleneck is the database and not the framework. A 10-100x slowdown in using an ORM or your framework of choice doesn't make much difference in terms of end user perceived speed (assuming you serve static content from a lightweight proxy web server). It does save a lot of money in cost-to-maintain.
Sure there is a place for optimised libraries and so on, but it's only worth optimising bottlenecks and the handler usually isn't one. I recently had to hand-write a TCP/IP server in Perl using POE to handle one particularly heavy case but most situations are easily dealt with by Apache mod_perl or FastCGI, in fact running Perl in CGI mode is often adequate. More important questions to me about frameworks are how: - easy to learn - quick to develop - flexible - comprehensive in terms of supporting infrastructure (templates, components) - easy/expensive to recruit staff - easy to integrate with other systems Realistic approaches include .NET J2EE Catalyst, Jifty RoR They all have strengths/weaknesses. For example, you'll get a Jifty or RoR app up quickly if you do it the standard way. If you want to build a bigger system that doesn't quite fit their model you're probably better off with Catalyst or another framework. I did one large system with Catalyst last year and it was great for that. I did a smaller system just before Christmas and wrote my own simple MVC framework for convenience. It's a question of choosing the right tool for the job.

Not everyone has the time or the know-how to do wheel reinvention and write custom daemons (I know I don't). That's why people write kernels and libraries and abstraction of lower level things so that others can build things on top. Otherwise we would never get anything done. _______________________________________________ List: Catalyst@lists.rawmode.org Listinfo: http://lists.rawmode.org/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.rawmode.org/ Dev site: http://dev.catalyst.perl.org/
