So the implementation of a GNU/Posix stack over windows is expensive and that is understandable (I suffer from cross platform headaches all the time). I knew that cygwin was somewhat slower than native Linux but I never took the time to make the measurements and seeing the numbers gave me a hope that maybe I had a simple configuration problem. If there was some magic bullet that could shave part of the expense from these types of operations I would gladly use it and that was why I posted my message.
While much of my development is done on GNU/Linux many, if not most, of my users rely on Cygwin/Windows as their primary run-time environment. Most don't recognize the performance penalty but it would have been great to swizzle the config make things X% faster. I appreciate everyone's insight and I will definitely checkout Mecklenburg's make book to get hard stats on the differences. -- 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/
