Xcode 6.0.1 poor performance

Question

I noticed that Xcode 6.0.1 has poor performance. Checked with Terminal command, here is the result:

~ MY_USERNAME$ ps aux | head
USER             PID  %CPU %MEM      VSZ    RSS   TT  STAT STARTED      TIME COMMAND
MY_USERNAME      496  99.9 17.3 28817056 1454748   ??  R    10:06AM  30:44.60 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Xcode/Overlays/Interface Builder Cocoa Touch Tool --socketFD 37

When I work on storyboard, it occupied all my CPU power for all the time Xcode is running. The storyboard only contains few empty View Controllers only. Moreover, simulator works very slowly in Xcode 6, compared to Xcode 5. Does anyone have solution to solve this performance issue?

Using Xcode 6.0.1 (build 6A317), Mac OS X 10.9.5, 8GB RAM, 2.8GHz i7 CPU

This worked for me: open your storyboard and disable and re-enable autolayout (in file inspector).
