Xcode 4.2 保存文件的速度非常慢/经常使用沙滩球 [英] Xcode 4.2 is very slow to save a file / frequently beach-balls

问题描述

我将 Xcode 4.2 用于 Lion/生产版本.之前版本的 Xcode 4 表现很好.

I am using Xcode 4.2 for Lion / production version. the previous version of Xcode 4 performed just fine.

每次我保存文件时，有时是随机保存，沙滩球会无缘无故地显示 5-10 秒.

every time i save a file and sometimes randomly, the beach-ball shows for 5-10 seconds for no apparent reason.

我正在使用 Subversion 来实现它的价值.

i am using subversion for what its worth.

我捕获了一个样本，它似乎在这里的某个地方:

i captured a sample and it seems to be somewhere in here:

推荐答案

你的系统上有杀毒软件吗?在关闭防病毒保护之前，我遇到了同样的问题.

Do you have any anti-virus software on your system? I had same problem until I turned off the anti-virus protection.
