Thanks, I know what is factorial :)

The 3.4.x version of GCC on Cygwin suffers performance penalty from SJLJ
implementation of exceptions that it uses. It could be that you are
being bitten by it. But without seeing the real code and the real
command line that you have used to compile the test executable, it is
hard to tell what is making it so slow.

Again, you will have to provide more information.
