>And, even when they are on average, implementing stuff on Assembly is no guarantee of speed. Quite often, higher level abstractions lead to optimizations that are difficult to replicate if one is operating at a lower level. When browsing Code Golf, most often than not, the fastest implementation is in assembler. And sometimes it can be 2x - 4x faster than next fastest implementation which usually is C++.
