I just did a small test with 10000
dynamic_cast in a loop. I captured the time with
gettimeofday(). The loop always completed in 4000-5000 microseconds.
(depending on the other system load. I did not close every app to
get a clean benchmark system).
So I don't really see a problem with dynamic_cast on Linux/gcc4
taking half a microsecond.

This is a 2.8Ghz P4 HT

Maybe you could do such a test on windows?
