I digged a bit deeper and found out that the GC activity comes only long after the following hot spot:
5054.0ms 41.0% -[PBXProjectIndexBTree(PBXProjectIndexBTreeEnumeration) valueForKey:at:]
2597.0ms 21.0% -[PBXProjectIndexBTree deleteValue:forKey:]
2597.0ms 21.0% -[PBXProjectIndex(PBXIndexingEngineCallbacks) _deleteFileAtLocation:]
2597.0ms 21.0% -[PBXProjectIndex(PBXIndexingEngineCallbacks) _finishIndexingFile:]
2597.0ms 21.0% -[PBXProjectIndex(PBXIndexingEngineCallbacks) _endSourceFile:]
2597.0ms 21.0% -[PBXProjectIndex(PBXIndexingEngineCallbacks) endSourceFile]
2597.0ms 21.0% -[PBXDevKitIndexingEngine indexFileAtAbsolutePath:withSettings:]
2597.0ms 22.7% -[PBXProjectIndex _indexBackground:]
2597.0ms 22.7% -[NSInvocation invoke]
2597.0ms 22.7% -[XCInvocationQueue _processNextInvocationInThreadSlotNumber:]
Meanwhile the main thread is idling:
193.0ms 21.9% -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:]
I filed it as a bug under rdar://8150096
It seems as if the project index causes the load. Might there be a workaround for me to make Xcode faster again. Maybe flushing the index or so?
Cheers

When I type some characters in the source code editor, the app gets slower and slower and after 10 characters or it gets totally unresponsive for about 4 seconds. I checked the activity of Xcode with Instruments' time profiler and found the following hot spots:
