I get 1.1 seconds on a low-end Core 2 Duo with WinXP. Something else also the matter at your end. (Of course, my Linux box, on an older Core Duo, also does this in 0.085 seconds, so your Linux box is slow, too :-) ). But process creation is well-known to be slow in Cygwin, for completely unavoidable reasons (having to emulate a nearly full layer of POSIX semantics *on top of* Windows processes, which are already slow(er) to start with). -- 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/
