Not enough information.  I created this exciting test application:

 #include <stdio.h>

 char i[132*1024*1024];

 int main ()
 {
   getchar();
   return 0;
 }

and started it under 1.5.9, casuing the commit charge going from 189 to
322 MB.  So what?  See http://cygwin.com/problems.html

Cygwin is emulating POSIX on top of Windows.  You'd expect some slowdown
for the overhead.
