Paul Jones has posted a teaser concerning his talks(s) at the upcoming php|works conference this year. One is about organizing your applications to make them easier to maintain and work better and the other is a follow up to some previous benchmarks he created comparing several of the popular PHP frameworks.
About The Benchmarking Talk - Easy one-liner: "Statistical Histories for Fun and Profit." And I do mean profit: the better your apps runs on a given stack, the more eyeballs you get on your ads (or, the more users you can handle).
He will be talking about why benchmarking your app is important, how to benchmark a framework and, the thing everyone's waiting for - his benchmark stats comparing several popular frameworks.
Paul also requests that, if possible, one developer from the teams of each of the other frameworks (besides Solar of course) could be in attendance to critique the talk and help point out issues either with the talk or in his methods.
