我最近了解APC(我知道,我來晚的演出),並決定嘗試一下我的開發服務器上。我做了一些基準測試與ApacheBench,讓我吃驚,我發現,事情正在運行慢比以前。APC讓PHP 5.3更慢?
我還沒有做任何代碼優化使用apc_fetch
或任何東西,但我覺得操作碼緩存應該對它自己產生積極的影響嗎?

這是我的php.ini中的APC部分。我最左邊的東西在默認情況下,除了不斷擴大的默認大小爲128MB,而不是32
[APC]
apc.enabled = 1
apc.enable_cli = 1
apc.ttl=3600
apc.user_ttl=3600
apc.shm_size = 128M
apc.slam_defense = 0
難道我做錯了什麼,或者我只需要使用apc_fetch /存儲真正得到好處APC?
感謝你們能給任何見解。
_「注意:在Windows上,APC需要一個臨時路徑來存在,並且可以通過Web服務器寫入,它按順序檢查TMP,TEMP和USERPROFILE環境變量」_此路徑是否存在? – Wrikken 2013-03-11 16:54:48
APC應該有所作爲......你有AB數字之前和之後,還是之後? – 2013-03-11 16:55:28
而且要知道,有很多其他因素的影響,如不良的數據庫查詢或文件訪問可以有一個很大的不利開銷 – 2013-03-11 17:12:36
