BitMagic benchmark test compiled on Windows XP under different compilers (GCC 3.4, MSVC 8 and Intel C++ 11). Tests here are synthetic, but represent very practical functions used in data-mining and database search algorithms. No SSE2 or 64-bit optimization, pure 32-bit mode, single thread. System is running on Core2 Duo.
BitMagic individual tests (shorter - faster)
Overall results (shorter - faster)
Test results are relatively uniform (code is rather well tuned manually), it was a bit of surprise to see Intel C++ 11 slower in XOR count test (Humming distance).
Overall winner for integer algorithms - GNU C++.
