Not us, but GCC does not support anything over -O3. -O4 and above are treated as -O3. I *really* wish people would have a clue with with in the hell they think they are achieving with -O<bignum>. Not all optimizations are appropriate in all cases. And given this level of optimization and the fact that the linux box is probably a different version of GCC, I wonder how much of this could be due to the compiler. Please rerun your tests with '/usr/bin/time -l' on FreeBSD and however you achieve the same on Linux. P.S. are you sure you are swapping, vs. paging?
