Hi. Laravel user/contributor here. I suggest you try the framework before judging it based on a benchmark. Not sure about their system/code, but a large production application with APC (Laravel 3.2.14, just like the benchmark) has a latency of 90-120ms, and some of those pages are pretty complex.
Techempower invites SMEs and advocates of their language/platform to submit pull requests to improve any overlooked performance problems in the specific benchmarks.
You're more than welcome to help make laravel look better in these benchmarks. But unless you're running the PHP through HipHop, I doubt you're going to get anywhere near the statically-compiled platforms near the top.
