那些大方舍得为你花钱的人，并不是多么富有，谁的钱都不是大风刮来的，而是他觉得你们的关系比钱重要，因为重要才舍得。透过云端的道路，只亲吻攀登者的足迹。
配置指令如下：
[opcache] zend_extension=opcache.so opcache.enable_cli=1 ;共享内存大小, 这个根据你们的需求可调 opcache.memory_consumption=256 ;interned string的内存大小, 也可调 opcache.interned_strings_buffer=8 ;最大缓存的文件数目 opcache.max_accelerated_files=4000 ;60s检查一次文件更新 opcache.revalidate_freq=60 ;打开快速关闭, 打开这个在PHP Request Shutdown的时候 会收内存的速度会提高 opcache.fast_shutdown=1 ;不保存文件/函数的注释 opcache.save_comments=0
实际性能对比：
下面是实际测试中没有开启opcache的数据：
