Xcode 4.2保存文件速度很慢/頻繁使用沙灘球

我正在使用Xcode 4.2 for Lion/production版本。以前版本的Xcode 4表現得很好。Xcode 4.2保存文件速度很慢/頻繁使用沙灘球

每次我保存一個文件，有時是隨機的，沙灘球顯示5-10秒沒有明顯的原因。

我正在使用顛覆它的價值。

我捕獲的樣本，它似乎是在這裏的某個地方：

你有你的系統上的任何防病毒軟件？在關閉防病毒保護之前，我遇到了同樣的問題。

我在我的系統上安裝了卡巴斯基AV，並且遇到了上述問題。停止AV應用程序阻止了沙灘球。可悲的是我的開發文件夾作爲排除在AV沒有解決問題，所以我沒有AV，而編碼。 :-( – Martin

我在使用代理的企業網絡中，在減速過程中運行wireshark並看到一些代理認證錯誤。我的理論是Xcode使用文件保存作爲更新內容的機會。我禁用了文檔更新並且它正在工作更好！ –

+1我發現Sophos在每次保存文件時增加了大約20秒的延遲 – progrmr
