Over on Reddit.com there's a flamewar...er discussion happening about this set of benchmarks (from 2011) showing things like response time, system load average and a function execution map for several popular frameworks.
In the Reddit comments most people share the similar ideas about the results:
- "I don't put much stock in hello world bench marks for MVCs. If you just need "Hello world" then write it in html."
- "Asking which framework is the fastest is almost irrelevant in most cases. I always dislike benchmarks like this because the actual situation is so much more complicated than a handful of benchmarks can show."
- "Any decent framework can output a simple content page from cache, it should not even have to call any router or controller. That's why simple content benchmarks are useless."
- "Who cares? The speed of a language or framework does not translate over to the speed of your website. What matters is your architecture."
If you're looking for benchmarks that are more useful than these, I'd suggest checking out (and maybe contributing to) the ones Paul Jones has created over on Github.
