PHP

メモリ消費とか

裸のPHPは実は結構速い。が、フレームワーク、特に最近一般的なMVCなものを挟むと数段重くそして遅くなる。

PHP MVC Framework Showdown: 7.1 Performance – Will Bowman – Medium

No framework: 7,094 requests per second, .34M memory.

Codeigniter 3: 2,245 requests per second, .38M memory.
Lumen 5.3: 1,543 requests per second, .63M memory.
Fuel 1.8: 1,033 requests per second, .60M memory.
Symfony 3.0: 551 requests per second, 1.52M memory.
Laravel 5.3: 331 requests per second, 1.53M memory
Zend 2.5: 291 requests per second, 1.34M memory

PHP開発元のZendが一番遅いのは笑うところ。
