Check in a customized benchmark which compares the Xcode 4.1 vs. Xcode 4.2's gdb disassembly speed
on lldb's Driver::MainLoop function which is ~1190 lines of x86 assembly code. This file is not
exercised during the normal test suite run, i.e., no +b option specified. So it should be ok.
The following is the benchmark result on my MBP running OSX Lion:
