PHP开启opcache提升代码性能

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:
