The first one is in Smart Reseller (a USA trade press magazine) at : http://www.zdnet.com/sr/stories/issue/0,4537,2196106,00.html titled : "The Best Windows File Server: Linux!". It covers Samba on Linux vs. NT on a single processor system (and confirms the rumours I've heard that Linux + Samba outperform NT with more than 12 users). The second becnhmark I must confess I helped with. This was done at PC Week (another USA trade press magazine) and was in a large server configuration. This was a VA Research 4 x 450MHz Xeon processor machine, with 18GB of storage in a RAID 5 configuration and 2GB of memory. This article may be found at : http://www.zdnet.com/pcweek/stories/news/0,4153,387766,00.html titled: "Linux: Enterprise-ready". There are no comparitive NT numbers in this benchmark. The reason for that is that NT on the multiprocessor box performed so poorly in the test (a factor of 5 slower than Samba) that both PC Week and myself were convinced that something was wrong with the NT tuning. The problem was that NT refused to use more that 300MB of memory for file cache (despite tweaking the only public setting that NT allows to modify this). Even searchin all Microsoft technical references and Web pages on NT tuning did not allow us to find anything to force NT to use more memory for disk cache. On the Linux side I used to documentation in /usr/src/linux/Documentation/vm to set the disk cache size to 80% of all available memory. Hope these numbers are interesting to people - use them as you will :-) :-). Regards, Jeremy Allison, Samba Team.
