squid通過coss給圖片做代理
不知道這樣做性能上面會不會有提供，
想通過squid給圖片伺服器做反向代理，
squid伺服器配置如下CPU：雙核雙至強Xeon3.2，內存：2G，硬碟：600G ata RH-E4/i386 squid2.7

《解決方案》
目錄正在測試環境中，還沒有放到生產環境，希望有經驗的朋友們幫我分析一下，看是用coss還是用aufs存儲
《解決方案》
object多的情況下，比如單機跑超過500萬個object，還是coss好，不過coss容易受單進程內存分配問題的影響，從而導致不響應請求的情況
雖然出現幾率很小，此時只要kill掉squid進程，重起就能恢復，coss還存在rebuild時間長的問題
