8.648266500000005s(repeat experiment) you can see that the three (win system can be three ways) execution time or there is a large gap. the execution time of Ubuntu on win is more advantageous than the virtual machine. But Cygwin's execution time is slightly less than Ubuntu on win.
Ubuntu on Win vs Ubuntu (virtual box) vs Cygwin
