On my 2009 MBP I noticed a significant performance decrease going from Xcode 3 to Xcode 4. It's not unusable, but Xcode 3 was quite snappy by comparison.
You can improve performance slightly in the code editor by turning off the code folding and live issues (which I didn't really care for anyway), but the integrated interface builder is horribly slower than the one in Xcode 3.
Of course now I've upgraded to a 2011 Macbook Air and Xcode 4 performance is now...acceptable.
