I built WolfSSL twice on the same computer - Windows 7 - Leveno Desktop Intel i5-4460 3.2 GHz. One build is using cygwin and the other with Visual Studio 17 Community C++. The Cygwin version ran 50 times faster than the Visual Studio version on the same computer! I got virtually identical benchmark results on a Windows 7 2.7 Ghz Intel i7 computer using Visual Studio 15 Professional C++.
I ran the two benchmarks using the same blocksize of 1024. The Visual Studio benchmark has a default blocksize of 1024 whereas the Cygwin benchmark program has a default blocksize of 1048756. When I set the Visual Studio benchmark blocksize to 1048756, I get all zeros:
