But the original poster wasn't just saying "Cygwin is slower than Linux" or 
"Cygwin is too slow". He also said:

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.
