Tim,

Very nice job on the testing methodology and the paper. It is this kind =
of
effort that increases the credibility of our technology niche and =
provides
real world, useful information. I hope that more of the senior =
consulting
types take the time to document and distribute this type of info.

thanks

Since this is a hot topic, I have posted the preliminary version of our =
WP
on Hyper-Threading at the following link.  Hopefully the graphics are =
more
readable than the Citrix paper;-)

http://www.tmurgent.com/images/WP_HyperThread.pdf

While we didn't look to max sustained users, we expect an average of 15%
performance improvement when you enable HT  in a TS environment with =
2003.

Ya, the bottom line of this doc is if you have 4 processors and turn it =
on
there isn't much worth to it. With 2 processors you get about 11%
performance increase. But looking at the charts it didn't seem very
significant in any one area and appeared that quite a bit less memory =
was
used if hyperthreading was turned off. JK

Is it just me or are the graphs on that page some of the least =
informative
around?

I also found this recent doc from Citrix site:
CTX101880 How Hyper-Threading Affects User Capacity of Metaframe XP =
Servers
http://support.citrix.com/kb/entry!default.jspa?categoryID=3D118&entryID=3D=

fromSearchPage=3Dtrue

(link will probably wrap)

Hmm found this document on Hyperthreading support from MS
http://www.microsoft.com/whdc/hwdev/platform/proc/HT-Windows.mspx

In it states:
        All versions of the Windows 2000 operating system are fully
compliant with HT and should run without error on HT-enabled systems.
However, neither Windows 2000 nor any of its service packs support the
identification of HT processors. The type of modifications that are =
required
for HT processor identification and support are not typically supported =
in a
service pack. There are no plans to introduce this support in any future
Windows 2000 service pack.
        As a result, Windows 2000 treats each logical processor as if it
were an individual physical processor. The operating system attempts to
start each logical processor in the sequence in which it was listed by =
the
BIOS until the number of processors that have been started is equal to =
the
processor license limit for that version of the operating system. Table =
1
shows the processor limits for Windows 2000 versions.
