I have just addressed a performance issue in XE4 (without update1). My parser benchmark program took 600ms when enabled Compile->Debug Information option in XE4. It only took 60ms in XE-XE3 with same project configuration. When I disabled the option in XE4, it is ok. (Optimization option doesn't have an impact in this case)

Did you meet this situation?
