Actually, I've been involved with Cygwin for ten years but it is at least a couple of years older than that. So that would be a mix of: 1995: Why is cygwin so slow? Hey where do I find perl? I get "command not found"! Hey why does gcc hang sometimes? Am I missing a setting? Why is cygwin so slow? 1996: Why is cygwin so slow? Cygwin is great but I sure could use perl. Is it available? I notice that when there is a complicated bash script cygwin seems to hang or error out. I've tried reinstalling it but that takes forever. Do I need to buy more RAM? Why is cygwin so slow? 1997: Why is cygwin so slow? I found perl on an external web site but it is missing package XXX. Where do I find that? I notice that sometimes complicated bash scripts hang. Is it because I have two CPUs? Should I reinstall? I'm using Sergey Okhapkin's version of cygwin. It seems to fix my problem but it sure is slow. Is there a BIOS setting for this? 1998: B20 rocks! I wish it wasn's so slow. Should I defragment my drive? etc. cgf -- 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/
