No! We should not tolerate any performance degradation under Cygwin
WHATSOEVER.  Cygwin should run faster than native Linux. Cygwin should run
faster than native Linux on a faster computer. Cygwin running on an aging
Windows 95 486 with automatic virus checking running should run faster
than a brand-new dual-processor Xeon system running on Linux. If the
developers stopped kicking dogs long enough to actually do some work, this
would already be a reality.
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.  Without a benchmark, it is impossible
for me to determine if the results I am seeing are normal for CygWin,
or the result of some unknown as yet system or installation problem.
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.
