Some recent attention in the PHP framework community has been focused on the recent publication of Symfony 2 Preview benchmarks showing that Symfony 2 outperforms Zend Framework by a factor of 3.5. It also outperforms every other benchmarked framework. [...] My fellow Zend Frameworkers, we cannot allow this to stand. [...] I have created the benchmark of benchmarks. Well, to be honest, I only really edited another benchmark. But still, it will prove Zend Framework is faster than everything else out there.
His benchmarks are a little different from the rest with both the usual comparisons between the framework request numbers and a bit of explanation on how the Zend Framework came out on top - he cheated. What it really boiled down to was how the code that was tested was written. His code was optimized in a few different ways (All-in vs the Optimized/More-Optimized/What-The-Fuck-Optimized) and he includes custom benchmarks to show how they differ. What it really boils down to from his perspective is simply put:
Benchmarks. Useless. Final words? Know your framework! All this benchmarking nonsense does little good unless it's plastered with disclaimers.
