When those micro-seconds matter

Catalyst is the only web framework that has a mailing list I subscribe to - but I am sure that it happens at others too. In a recurring pattern someone someone posts a benchmark showing that Catalyst for some trivial operation is many times (or many hundred times) slower than some other web framework or for that matter PHP. That does not fail to generate a heated debate - but eventually the seasoned framework developers gain the upper hand with the argument that for all the, often big, web sites they worked on, those few micro-seconds lost in the Catalyst dispatcher never mattered much because the application spent hundred times more in other code fragments and mostly in business logic parts, so shaving off some part of the few micro-seconds would not improve the overall speed more than 1%. This is a great argument, perfectly reasonable and rational but it is biased towards the status quo. It might be true that everywhere where Catalyst is currently used it works great but it is also not hard to imagine an application with very simple business logic that needs to serve millions of users, Twitter anyone? Or an app that does many simple Ajax callbacks. Sure you can always code the speed requiring, simple parts in PHP and keep Catalyst only for the other more heavy-weight tasks but having a universal solution would be so much more convenient.
