伺服器負載超高，可能與phpwind有關，大家幫忙看看！
內部的一個工作論壇，用phpwind，用二級域名和目錄訪問都超慢，伺服器負載很高，wc -l httpd進程很多，apache worker方式工作，因為沒有root許可權沒法修改httpd.conf，配置文件中沒有對worker模式進行配置（限制），不知是不是因為這個原因，還是程序上有問題。請遇到過類似情況的朋友幫忙看看！不勝感激！！

1.負載很高.速度是正常的.
load average: 75.07, 75.13, 74.58
2.從你提供的情況分析來看是APACHE的問題.具體問題分析,需要你提供
apache的配置文件
apache的錯誤日誌
系統日誌
根據以上三個方面分析一下原因

但是主站的cms和discuz跑得很好！！所以我懷疑是phpwind，或許是配置問題，不知大家看過沒？？

apache載入的無用模塊太多嗎？
《解決方案》
沒仔細看你的配置
但你的httpd進程佔用了太多的內存和cpu
特別是內存的佔用，是非常不正常的，問題應該是出在這裡
再具體的原因還要看到了才知道

phpwind 的問題，把它一走後負載馬上下來了，沒找出原因！！

問題一：樓主的 phpwind 與cms discuz 在同一台機器？
問題二：配置文件無用內容太多 用的worker 也可以，但是配置優化沒有貼出來呀。
grep -v "#" httpd.conf 過濾下#號。
由於 phpwind 引起的話，可以對phpwind 進行調整 phpwind 我不是特別了解。
但可以先優化 APACHE PHP
如果不行可以換成nginx 試下。

phpwind 本公司也是用這個呀，怕
