Saw this on yesterday's slashdot news:
	http://www.mindcraft.com/whitepapers/nts4rhlinux.html
I wonder how well FreeBSD would perform.

And what are the chances that anyone would trust the results of this
test after what they did to Linux and Novell? :) Seems to me like it
would be a waste of the kind of money they're likely to charge (and if
it were anything less than $10K, I'd be amazed).

What is the possibility to have a platform simular to the one Mindcraft
used and do our own testing ? Then do not repeat the errors they did.

Invite someone from the Linux community to participate and also someone
who could tune an NT box. I wouldn't mind to do something like that.

Well, does Linux really limit itself to 960MB of RAM as they claim?
If so, I'd say it's not an unfair test to not limit NT to the same low memory
use.
If on the other hand they limited Linux to 960MB of RAM by not doing proper
tuning, that's another matter...

Guess I better go read up on the Linux people's opinion on the testing...

It looks as if they did.  To quote
http://www.lwn.net/1999/features/MindCraft1.0.phtml, which I found to
be a well-reasoned summary, though I didn't check their reasoning:

  Non-issues

      A few complaints that have been sent to us probably do not
      figure into the test results. We list them here in the hopes of
      helping to slow their propagation and improve the quality of
      information out there.

         Some complaints have been raised about the test being run on
         a 4GB server, even though the Linux kernel, in its default
         form, can only use 960M of that. Patches can be applied to
         make 2GB available fairly easily. But, in any case, they
         claim that NT was limited (with the maxmem parameter) to 1G
         of memory, so this aspect of the test was fair. It would have
         been more straightforward of them, however, to have simply
         remove the other 3G from the system.

I can loan you a quad Xeon with 1GB of memory if you like (better
bring your truck though) but I can't say much about the actual
benchmarking software you'd use or how you'd simulate (or obtain) the
number of client machines they used.  That remains an open question for
which I've no practical answers.
