[OT] Microsoft claim 267% better peak performance than linux?

[OT] Microsoft claim 267% better peak performance than linux?

[Andrew Walrond]

I was pointed to this (rotating) banner advert at the top of www.eweek.com

It claims that when comparing Red Hat AS2.1 with Windows Server 2003 on a dual processor machine, Windows Server 2003 gives 276% better peak performance, quoting Veritest as the source.

I think the report in question must be this one

http://download.microsoft.com/download/0/7/1/0715a190-70f5-4b0d-8ced-f9d1e046aa6a/netbench.pdf

Its dated April 2003, so this was probably discussed a long time ago, but can anyone point me in the direction of an analysis/rebuttal of this report from the linux community? "Windows webserver gives 3x performance of linux" is something I need to be able to debunk, assuming it's inaccurate.

Wrong link. This is the one

Just the fact that the benchmark is this old, is a good reason to doubt
it.

The document shows some interesting points though:
- They describe what they did to make redhat/apache perform better
- ISAPI is pretty fast compared to CGI (Didn't apache recently release a
programming interface which is cross platform and does something like
this too?)
- Multithreading works in their advantage (Compare 2003 normal against
multithreaded, maybe too little amount of apache threads running, or
some optimization needed in the linux kernel here?)
And last but not least:
WIndows 2003 suddenly realizes that is has a few CPU's left and starts
using them (-: See the graphs where there is a weird bent in the 8 CPU
curve.

And it still doesn't matter actually: 286% faster is still about 3 times
more expensive, which is the point on which is must be compared (lower
TCO because we are faster, so MS TCO is lower, but still too high)

helo denis,
helo andrew,

denis is right, in my opinion, ms would never publish a docuemnt which
shows that linux is much more faster then there own priducts.

i would like to recommand a book to you, andrew. the book rebel code
written by glynn moody ia a great funny book which deals with the open
source philosophy and the bad benchmark tests.
it also explains how many the linux community influenced the set up of
the test machine in relation to microsoft.

you should read it, it's a great book.

Of course ISAPI is faster than CGI. The same happens with NSAPI. 
However, both are proprietary, have a steep learning curve, and 
usually, xSAPI extensions run on the same address space as the Web 
server, improving performance but decreasing stability. However, CGI 
runs as a separate process which adds a lot of overhead. There are 
solutions like FastCGI with less overhead and that allow persistence 
(the executable CGI is not destroyed, but stays in memory waiting for 
future requests).

MS commissioned studies are totally useless: they only probe what MS 
wants. If MS wants us to believe earth is flat, a MS commissioned study 
will reveal so.

If they ran it on a 2.6 release, these numbers are probably accurate 
with some of the memory sickness. AS looks like a middleware component.

It is very easy to 'slightly' misconfigure Linux machine so that it
slows to a crawl. For webservers, classic way to do it is to force
Apache to log a fqdn of incoming connections instead of numeric IP.

Do you seriously expect that MS-funded tests can ever find Linux
to be faster?

Yeah, like running 2.4.9 kernel... why not 2.0.0 kernel? ;)

Also, see page 33:

Operating System                  Key Exchange Algorithm       Message Digest
Windows Server 2003               RSA RC4 (128-bit)            MD5
Red Hat Linux Advanced Server 2.1 Diffie-Helman 3DES (168-bit) SHA1
Red Hat Linux 8.0 Professional    Diffie-Helman 3DES (168-bit) SHA1

and:

...
Set HKLM\System\CurrentControlSet\Control\FileSystem\NtfsDisableLastAccess to 1.

Reminds me  in the Apple studies  in the mid-90s when  they were still
technologically behind.  They always  issued that Apple computers were
faster  than  Linux/BSD  in  some strange  benchmark  under  unnatural
conditions.

Didn't Microsoft once compare Windows 2000 against Linux 1.2?
