   PHP开启opcache提升代码性能

        APC在PHP5.4及以下版本是性能最好的代码缓存。不过PHP升级到5.5及以上后,APC不再有效。需要使用Zend的OpCache扩展。

  配置指令如下:

 PHP开启opcache提升代码性能

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 [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:
