Move away all of the *.hdp files in your BCB6 lib directory. These are used by the IDE to try to optimize precompiled headers for smaller apps (where the user is less likely to do the optimization himself). The increase in the number of these files in BCB6 could be the cause of some slowdown at compile time.
My compile times in sec: BCB 5 = 217 BCB 6 = 1552 without *.hpd = 231

I just found hdp-files on my machine in the directory "include/vcl". After removing the my compile time is also a bit shorter, but not as in your case:
Having run tests this morning I can say that removing the HDP files gives significant speed gains. It depends on the project (presumably it's not a linear speed penalty) but for most of our projects we see a halving of compilation times.
