I have Win7x64 and Win10x64 VM's on the same physical Mac, both configured 
identically WRT disk, memory, etc. Both were just updated from setup, so are 
running same version of cygwin. 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 or so.)

I ran cygpath 100 times in a loop (for i in {1..100} …), using the loop 
variable as the parameter to cygpath. I ran each loop three times, then 
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.
