PHP開啟opcache提升代碼性能,php開啟opcache代碼


配置指令如下:

[opcache]
zend_extension=opcache.so
opcache.enable_cli=1
;共享內存大小, 這個根據你們的需求可調
opcache.memory_consumption=256   
;interned string的內存大小, 也可調
opcache.interned_strings_buffer=8
;最大緩存的文件數目
opcache.max_accelerated_files=4000
;60s檢查一次文件更新
opcache.revalidate_freq=60
;打開快速關閉, 打開這個在PHP Request Shutdown的時候 會收內存的速度會提高
opcache.fast_shutdown=1
;不保存文件/函數的注釋
opcache.save_comments=0 

實際性能對比:

下面是實際測試中沒有開啟opcache的數據:
