I'm not surprised. Very little time has been spent optimizing cygwin.dll or bash. Bash currently uses fork() instead of spawn() which costs it quite a bit of time. The Cygwin32 layer also needs performance analysis. Until that happens, it will be slower than it needs to be. > Any ideas since at this performance, I would have to buy the UWIN > package and I would prefer not doing it.... You could either buy UWIN or improve cygwin.dll and/or bash and send us patches. :-) -- Geoffrey Noer noer AT cygnus DOT com - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
