        To turn it off on my new DL380,=20

        Reboot Server
        Hit F10 for System Maintenance
        Got to Setup Utility
        Advanced
        hit Enter Processor Hyper-Threading
        Choose Disable
        Hit Esc, Esc F10 to save

I have just purchased a new HP Proliant ML370 2x1.4Ghz Xeon running =3D
W2KSP2 for my second Citrix server, and this is showing four processors =
=3D in task manager.

My other Citrix server (a Compaq Proliant ML570 2x1.0Ghz Xeon also =3D
running W2KSP2) is (only) showing two processors in task manager.

The server is not live yet...my question is, is having this =3D
hyper-threading on for a Citrix server a good thing or a bad thing?  If =
=3D it is recommended to switch it off how do I do that?

(Server will have about 15-20 users on it at any one time running word, =
=3D excel, outlook and a few custom apps..and...all users will be running an
= =3D access front-end/sql back-end application) on it).

Thanks,

Steve

I have Windows 2000 server running and hyper threading seems to be just =
=3D =3D3D fine.

Whether or not I am getting any kind of performance boost from it is a = =3D
=3D3D whole other debate but I have two physical processors in the machine
and = =3D =3D3D when I look at task manager, I see four.

        Our DBA is under the impression that Windows 2000 Server does NOT
support
        hyper-threading, but Advanced Server does. Is there any validity to
this? The
        only thing I see on Microsofts site deals with Windows XP. Any
ideas?
