PHP開啟opcache提升代碼性能

APC在PHP5.4及以下版本是性能最好的代碼緩存。不過PHP升級(jí)到5.5及以上后，APC不再有效。需要使用Zend的OpCache擴(kuò)展。

配置指令如下：

[opcache]

zend_extension=opcache.so

opcache.enable_cli=1

;共享內(nèi)存大小, 這個(gè)根據(jù)你們的需求可調(diào)

opcache.memory_consumption=256

;interned string的內(nèi)存大小, 也可調(diào)

opcache.interned_strings_buffer=8

;最大緩存的文件數(shù)目

opcache.max_accelerated_files=4000

;60s檢查一次文件更新

opcache.revalidate_freq=60

;打開快速關(guān)閉, 打開這個(gè)在PHP Request Shutdown的時(shí)候 會(huì)收內(nèi)存的速度會(huì)提高

opcache.fast_shutdown=1

;不保存文件/函數(shù)的注釋

opcache.save_comments=0

實(shí)際性能對(duì)比：

下面是實(shí)際測(cè)試中沒有開啟opcache的數(shù)據(jù)：
