Re: uptime not reporting CPU usage on Windows 7 (Possibly only when running in VMWare)

Nor did I say that you did. See the "You'd be"? That's short for "You
would be". And no, it wasn't meant entirely seriously.

Blah, blah, blah. Let's say I was extrapolating from this: "Well that
sucks. Surely Windows has some means of reporting how busy the system
is. uptime should use that.". Like the rest of your posts in this
thread, that's dripping with the assumption that you know best and
that the Cygwin devs haven't looked into this properly, while failing
to provide a single new insight.

Well, if you take the 0% at face value even though you know the
machine is doing something, you're being rather silly.

But I agree, I think it would be better not to provide /proc/loadavg
(which is where uptime gets the data from) in the first place if it's
not going to provide actual load averages, although I expect there was
some reason to provide a dummy implementation.

Because people would waste their time proving that it doesn't do what
it's supposed to and then email about it. Also, load information is in
fact already available from /proc/stat. Here's how to interpret it:
http://www.linuxhowtos.org/System/procstat.htm. That's what 'top' uses
as well.
