We didn't rewrite std::bitset. We found that it was simply being used to wrap an existing 32-bit word, and then pull a specific bit out. There are easy ways to do that: bool getBit(uint32_t word, size_t pos) { return (word >> pos) & 0x1; }

By "We replaced this with manual operations", do you rewrite std::bitset, or hack it? I also have bottleneck at the std::bitset.
