MinGW 还是只有老而稳定的 3.4.5。他们也没什么理由去更新它。
我看过 3.4.5 编译出来的 SHA 反汇编代码，完全看不出还有什么优化空间。我想象不出还能再挤出 8%。Windows 有可能有 8% 的额外开销吗？没有系统调用之类的，只是纯粹繁忙的计算代码，任务切换和其他管家操作会耗掉这么多吗？

MinGW still only has good old stable 3.4.5. There's not much reason for them to update it.
When I looked at the 3.4.5 compiled SHA disassembly, I couldn't see any room for improvement at all. I can't imagine how 8% more could be squeezed out of it. Is it possible Windows could have 8% more overhead? Not making system calls or anything, just plain busy computational code, could task switching and other housekeeping operations take away that much?
