Hi All,
I realise this relates more to Linux, but in my company which if
full of NT Fanatics they are taking this as gospel and using it as an
argument that NT Rules and Linux and FreeBSD cant do the job! Can
anybody point me to similiar benchmarks that dispute the letter below ?
regards,

> 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,

> http://www.mindcraft.com/whitepapers/nts4rhlinux.html.
>
> 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

> RAID
> controllers and SMP at the same time," said Mindcraft's president,

> 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

> performance collapsed with a WebBench load above 160 client test
