Hyper-Threading Technology

Win2k does not support hyperthreading. You will see
performance issues. Dealt with it on my system until I
found the documentation on it. Once I turned it off, alot
of problems went away.
 
Check out the link below. Hyperthreading will be a benefit for some situations, for others it may not prove to increase performance (and in some cases, HT will actually be a hindrance). It is best
to test in your particular environment before deciding whether or not to use it. Windows 2000 is not optimized for HT like Windows Server 2003 is. The link here will give you more information on the
subject.

Per my earlier post please see the information from Intel.

Note: Information on Hyper-Threading Technology ? for
Intel® XeonT processors is available here.

Microsoft* Windows* Operating System Desktop Based PCs
The following desktop operating systems include
optimizations for HT Technology and are currently eligible
to carry the new Intel® Pentium® 4 Processor with HT
Technology logo:
Microsoft* Windows* XP Professional Edition
Microsoft* Windows* XP Home Edition

The following desktop operating systems are not
recommended for use with Hyper-Threading Technology. If
you are using one of the following desktop operating
systems, it is advised that you should disable Hyper-
Threading Technology in the system BIOS Setup program:

Microsoft Windows 2000 (all versions)
Microsoft Windows NT* 4.0
Microsoft Windows Me
Microsoft Windows 98
Microsoft Windows 98 SE

Linux* Operating System Desktop Based PCs
The following Linux operating systems include
optimizations for HT Technology and are currently eligible
to carry the Intel® Pentium® 4 Processor with HT
Technology logo:
Red Hat Linux* 9 (Professional and Personal versions)
SuSE Linux* 8.2 (Professional and Personal versions)
Red Flag Linux* Desktop 4.0
COSIX* Linux* 4.0

Note that while other Linux operating systems may have HT
Technology enabled, only the distributions above are
currently eligible to carry the Intel Pentium 4 Processor
with HT Technology logo. If purchasing a PC based on a
different Linux operating system, check with your PC
vendor to determine if the PC includes the necessary
system ingredients for HT Technology and has HT Technology
enabled.
