Sorry, but that blog post has severe quality issues. Is the skipfield now an counter per block or a bitfield? Why didn't they add std::deque to the comparison? Why is iterating through std::hive slower than std::list? They talk about SIMD and say "we can check this", but then it's about locality. Why didn't they measure iteration speed and memory overhead after random element removal?
