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?

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.
