But the original poster wasn't just saying "Cygwin is slower than Linux" or "Cygwin is too slow". He also said: >It is not entirely clear to me that my performance is representative >of other CygWin installations.

Which is a valid point. What is "normal" for Cygwin on given hardware, and what is "slower than normal"? Now that we have a benchmark, we can start to answer those questions. That's a useful thing. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
