The system calls go through cygwin1.dll and not directly to the system (for every for executable linked against cygwin1.dll). You may speed up your compiler if you build it optimized for your platform. The distributed gcc is compiled for arch=i486, optimized for your processor would result in a speedup about 20-30%.
