Hmm... Are these from Cygwin's shell? Is it possible that these
timings do not reflect actualness due to your native program would not
use the Cygwin runtime? Are you comparing apples to apples? You
might want to find some real measuring software. I've also noticed
that times can be skewed by the caching within the drive controller as
well.
I ran the tests several times, and the timings seemed to be pretty
stable. Also, it was mostly stat'ing the same files
over and over again. So, things should have been very cached for the
most part. The numbers are in line
with what we found with cmake about a year ago. At that point we were
using a profiler. I was running this
from the a cygwin shell, and I compiled the program both with and
without the cygwin compiler. I know with
cmake we saw at least a 2 fold speed up when we went from _stat to the
native windows calls.
