Both were on newly started mintty's, and,= in the case of Win7, just-started VM. (My Win10 VM has been up for a day o= r so.) I ran cygpath 100 times in a loop (for i in {1..100} =E2=80=A6), using the = loop variable as the parameter to cygpath. I ran each loop three times, the= n averaged the times. Thus the times below are for 100 cygpaths. On Win7, times were .790/.145/.396. On Win10, times were 1.340/.350/.650. Not enough for me to worry about, but it might be for you. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
