[p4] New Windows profiling script in public depot

[Frank Compagner]

Sorry, reposted, now with a proper subject.

Hi. I've just added a Python script to profile a Windows Perforce
server to the public depot at:
http://public.perforce.com:8080//guest/frank_compagner/

This has proved quite useful in figuring out where the performance
bottlenecks in our Perforce setup currently are, so hopefully other
people will find it helpful as well.

Detailed documentation is at the top of the script, here's the
summary: The script requires both a Windows server and client (where
the script will run), and both Windows and Perforce admin access to
run properly. It runs continously, giving you some general stats on
the server machine: cpu load, network & disk usage, as well as the
cpu & memory load of the p4 server process. It lists details on all
running Perforce threads, so you can easily see what the server is
doing and if it's having a hard time doing it. Proxy and client stats
can be monitored too to make it easier to track down bottlenecks in
your setup.

Some sample output:

CPU: p4s =  33%  Idle = 66%  Other =  0%    MEMORY: p4s = 2000 MB / 470 MB
NETWORK: 10 MB/sec    DISK: db =  4%  depot = 10%

I'm working on a *nix version of the script, and I also want to turn
this into some sort of webpage to make it easier to access. When that
happens, I'll let you know.

If you have any comments or questions, let me know.
