There are a lot of ways to use semantic which changes its performance 
profile.  It depends on what features you want.  Most configuration help 
assumes you want all the most time consuming features, but there are 
also simple helpful features that are supported with minimal parsing 
support.   To boot, C++ is also the oldest parser in the suite and it 
wasn't updated to the newer/faster parser generator.

While I haven't had time to work on CEDET  lately, I'd be happy to 
discuss specific performance issues and share ideas on how to improve 
them, presumably after the most recent merge is completed.
