Re: [boost] sorting floats by casting to integer

I've been investigating why float_sort is so much faster than std::sort on x86 processors, and why sorting integers is so much faster than float_sort, and came to the conclusion that floating-point comparisons are extremely slow on x86.

Hey Steven, Is it true even with SSE3 optimizations turned on and data aligned to 16-bytes boundaries? Which compiler were you using?
