hi guys, i think cygwin is great, and i'd like it to be more useful to me. my work for the past year has been porting daemons to windows. so i'm familiar with the fork problem. i've read a little about how cygwin does a lot of work to make fork work. -- and to make it work without having to change the source from the vendor. i think maybe the vendor might be changed to make small changes to their source so that cygwin will run a lot better.
a little example that illustrates cygwin's fork efficiency is: $ time ls >/tmp/out real 0m0.131s user 0m0.062s sys 0m0.015s $ time for x in `cat /tmp/out`; do ls -d $x; done >/dev/null real 0m3.512s user 0m0.378s sys 0m0.915s which kind of kills some simple shell scripts. in the example, i guess all that is done is to fork and exec ls, grabbing its stdout. this can be done with CreateProcess() easily without having to emulate everything that fork does. so my real question is, has anyone tried optimizing fork/exec to CreateProcess()? and would the maintainers of (eg. bash) accept a patch for use with cygwin? (so i wouldn't have to continually forward port my fork/exec code). ta, jack -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
