I do not think this has anything to do with your OpenOCD problem. Cygwin is known to be slow. MSys is faster but still slower than Linux. I do not know what you want to show by the bash commands though. Anyway, here are my results on a Core i5 Notebook (Dell Latitude E6410, XP SP3, Latest Cygwin). bash-4.1# time echo "blah" blah real 0m0.002s user 0m0.000s sys 0m0.000s bash-4.1# time echo "blah" | cat blah real 0m0.197s user 0m0.045s sys 0m0.124s bash-4.1# time echo "blah" | cat blah real 0m0.128s user 0m0.061s sys 0m0.092s bash-4.1# time echo "blah" | cat blah real 0m0.102s user 0m0.061s sys 0m0.061s bash-4.1# time echo "blah" | cat blah real 0m0.056s user 0m0.061s sys 0m0.046s bash-4.1# time echo "blah" | cat blah real 0m0.088s user 0m0.061s sys 0m0.045s bash-4.1# time echo "blah" | cat blah real 0m0.103s user 0m0.061s sys 0m0.077s bash-4.1# time echo "blah" | cat blah real 0m0.105s user 0m0.061s sys 0m0.045s bash-4.1# time echo "blah" | cat blah real 0m0.096s user 0m0.045s sys 0m0.061s bash-4.1# time echo "blah" | cat blah real 0m0.101s user 0m0.061s sys 0m0.046s bash-4.1# time echo "blah" | cat blah real 0m0.096s user 0m0.045s sys 0m0.061s -- Xiaofan _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
