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:
- [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:
