Bug with starting Instruments via Profile under XCode 4.1 Build 4B110
Instruments used to work fine, however now that I have the new 4.1 Xcode on Lion, it is extremely slow and I have to wait about 5 min before it is responsive. Is anyone else having this same problem? I am using iOS simulator too.
I have already tried reinstalling and uninstalling Xcode a few times as well.
