Xcode compile time very slow after upgrading to Mavericks

I am using Xcode 5. When I had Mountain Lion installed, doing a build after a clean took less than 10 seconds for my project. It was extremely fast.

After upgrading to Mavericks, doing a build after a clean now takes about 2 minutes for my project. It takes almost one second to compile each source file! The source code is exactly the same as the code before the upgrade, so I know that this problem is definitely caused by the Mavericks upgrade.

Running the top command shows about 15 clang processes during build time. Each clang process keeps switching from the "sleeping" and "stuck" state. So I'm wondering if this issue has something to do with race conditions with the multiple clang processes.

So far I have tried rebooting, and reinstalling XCode.

Edit

Other Info: I'm using the latest macbook pro with retina display with 16GB of ram. I also have file vault enabled. Will try disabling it to see if it changes performance.

I've solved the problem. Turns out it was my virus scanner McAfee. It must have been scanning every source file before letting Xcode compile it. The weird thing is the virus scanner was taking up almost no cpu cycles.
