開啟opcache擴充套件效能前後比較

阿新 • • 發佈：2019-01-11

終端使用ab測試

開啟前

在本地請求10000 併發200 看看處理情況

剛開始不穩定,瞬間併發,可能直接崩潰,要不就是響應時間超級慢,可以都測試幾次取平均值

只想說開啟opcache後 ,效能提升不少

做個比較

就單看第三項

Requests per second:   xxx [#/sec] (mean)吞吐量-每秒請求數
Time per request:      xxxx [ms] (mean)伺服器收到請求，響應頁面要花費的時間
Time per request:      xxx [ms] (mean, across all concurrent requests)併發的每個請求平均消耗時間
延長的問題

根據自己的需要選擇自己需要配置的選項

[opcache]

由於我使用的是mamp環境 nginx+mysql+php

php5.6版本

我使用的是預設的配置

這只是在本地測試,end opcache會自動在記憶體中快取預先編譯好的php位元組碼，如果快取了某個檔案的位元組碼，就執行對應的位元組碼

因為PHP是弱型別語言,不能直接被機器識別,需要 zend 引擎處理,經過詞法分析語法分析,處理成opcode(operator code)

順便說一下PHP7中增加了抽象語法樹的概念.

再來看

開啟opcache前後

cache misses 未命中數 35

使用記憶體12583384

開啟後測試

cache hits 命中數 34326

cache misses 未命中數 54

使用記憶體13610472b

瀏覽器訪問方面我們可以對比看到

讓子彈飛~利用 OPcache 擴充套件提升 PHP7 效能 | Laravel 篇

PHP在執行的時候，存在這樣的一個流程，先將PHP程式碼預編譯，生成位元組碼後再載入到記憶體裡，最後CPU在記憶體上執行編譯後的位元組碼片段。我們會發現，在執行PHP程式的時候，每次都經過這樣的流程，此非浪費Time，是的，很容易聯想到：為何不向C++語言看齊呢，將原始碼編譯成可直接載入到記憶體so哥呢？
