Ok all, I just got this on HP's internal Open Source news scan.
I haven't been able to find the link on the web yet - can anyone
help me track this down ? The publish date is next monday, so
it may not be on the web yet.

If so I'm going to trumpet this to HIGH HEAVEN ! Looks like we
do well when you don't tune the server :-).

(Maybe all that last minute cachegrind work paid off :-).

Jeremy.

ITWEEK Enterprise Week - Samba trounces Windows.

Tests by IT Week Labs indicate that the latest version of the
open-source Samba file and print server software has widened the
performance gap separating it from the commercial Windows alternative. 

Samba is an open-source implementation of the Common Internet File
System (CIFS) protocol used for file and print sharing by PCs running
Microsoft Windows. Samba 3, released last month, is a long-awaited
upgrade that adds important new features, most notably compatibility
with Microsoft Active Directory. 


Version 3 can be set up to authenticate users from an existing Active
Directory. 

The latest benchmark results show an improvement over version 2, which
performed twice as fast as Windows when it was tested by IT Week Labs
last year. Overall, it now performs 2.5 times faster than Windows Server
2003. 

In terms of scalability, the gains of upgrading to Samba 3 are even more
striking. Last year we found that Samba could handle four times as many
clients as Windows 2000 before performance began to drop off. This year
we would need to upgrade our test network in order to identify the point
where Samba performance begins to fall in earnest. 

IT managers say Samba's better performance means they can use cheaper
servers than would be possible with Windows software. And if they run
Samba in a completely open-source environment, such as on Linux, they
could remove the cost of Windows server licences. Samba is available
free of charge for commercial Unix versions including IBM AIX, HP-UX and
Solaris. 

It is also available for various versions of Linux, Novell NetWare and
VMS. 

The IT Week Labs tests used Ziff-Davis NetBench file server benchmark
with 48 client systems. We selected a low-specification but otherwise
modern server for our tests. We used an HP ProLiant BL10 eClass Server
fitted with a 900MHz Pentium III chip, a single 40GB ATA hard disk and
512MB of RAM. We did not tune any of the software to improve
performance. 

Each NetBench client makes a constant stream of file requests to the
server under test, whereas in real-world environments many users would
remain idle for long periods. Consequently our test environment
simulates the workload of some 500 client PCs in a typical production
environment.
