Report: NT 3.5x Faster Than Linux
  This issue of W2Knews™ contains:
Hi All,

As most of you know, when some important news hits the
wires we will inform you immediately. This morning I
found something in my in-box that will definitely throw
some more gasoline on the raging 'NT vs Linux' fire.

I quickly read through the report and could not find
anything wrong with it at first observation. The numbers
seem to be correct, as they are using an industry standard
benchmark that I have used myself as well, the ZD bench.

Oh, before I forget, Novell actually wrote a rebuttal 
against that last report that SMS is better than ZEN.
Interesting reading, and this gives the Novell POV:

But here comes today's bomb in the NT vs Linux battle.
One wonders who pays for these tests but I will ask the
CEO of MindCraft and report on that in the next coming
newsletter. Here goes!

LOS GATOS, Calif., April 13. Today, Mindcraft released the results 
of a study comparing the performance of Red Hat Linux 5.2 (updated 
to the Linux 2.2.2 kernel) and Microsoft Windows NT Server 4.0 
operating systems. According to the report, Windows NT Server 
provides over three and a half times the performance of Linux as a
Web server. Furthermore, the report shows that when testing Windows 
NT Server and Linux as file servers, Windows NT Server provides over 
two and a half times the performance of Linux. The full report,
including all of the details needed to reproduce the tests, is on
Mindcraft's Web site at:


Using benchmarks from Ziff-Davis Benchmark Operation (ZDBOp), the 
report compares the peak performance levels of both Windows NT 
Server and Linux configured both as a file server and a Web server. 

All tests were performed on a standard Dell PowerEdge 6300/400 server 
with four 400-MHz Xeon CPUs, 1GB RAM (960MB for Linux -- this is the
default maximum amount of RAM that Linux supports). To simulate a 
client load, Mindcraft used 144 physical client test systems; half 
were running Windows 95 and the other half were running Windows 98. 

Both Linux and Windows NT Server were tuned to perform optimally under
each of the two workloads. "We started the tests using standard Red Hat
Linux 5.2 but had to update it because it does not support hardware RAID
controllers and SMP at the same time," said Mindcraft's president, Bruce
Weiner. "Linux definitely takes more time and resources to tune and to
configure than Windows NT Server. You have to search the Net to find the
latest kernel and driver versions to get the highest performance and most
reliable modules. Then when you're done, Linux fails to deliver the same
level of performance as Windows NT Server on enterprise-class servers."

Mindcraft's report shows that using ZDBOp's WebBench 2.0 Web server
benchmark, Windows NT Server and Internet Information Server (IIS) 4.0
reach a peak of 3,771 requests/second and 22.4 Megabits/second(Mbps) of
throughput. The report goes on to show that Linux and the Apache 1.3.4 
Web server reach a peak of 1,000 request/second and 5.9 Mbps of
throughput. The WebBench 2.0 tests also revealed that there are problems
with Linux/Apache at high client loads. "The Linux/Apache Web server
performance collapsed with a WebBench load above 160 client test threads,
while Windows NT Server/IIS continued to increase performance up through
288 client test threads without reaching their peak performance," adds 
Mindcraft's Bruce Weiner.

To simulate a file server workload, Mindcraft used ZDBOp's NetBench 
5.01 benchmark. The testing revealed that Windows NT Server performance
peaked at 286.7 Mbps with 112 clients, while Linux running Samba 2.0.1
peaked at 114.6 Mbps with only 48 clients. "The integration of the SMB
file sharing protocol with the multi-processor kernel is a key performance
win for Windows NT Server," said Weiner. "Customers benefit every day from
the superior scalability of Windows NT Server, which delivers vital file
and web services at two to three times the performance of Linux as shown
in these benchmarks," said Edmund Muth, Group Product Manager, Microsoft
Corporation. "Empirical data like this helps customers and planners make
informed decisions, and showcases the industrial strength technology and
mature engineering of the Windows NT Server operating system."
