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. - -- VH -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iFYEAREIAAYFAkkXG70ACgkQhQBMvHf/WHn0hQDcDoSm5pFW64ZMcBIJe/5V1hZO 0JjPtkE4PsE5iADfW7cXdHw8Bo+DnbhA5EXhvYhPSVy7vb9THZ9V/Q== =4nRA -----END PGP SIGNATURE----- -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
