Hyper-Threading

Hyper-Threading is an Intel® technology that can enhance overall performance by allowing one physical microprocessor to function as two logical
microprocessors, capable of performing certain tasks simultaneously. It is recommended that you use the Windows XP operating system because Windows XP
is optimized to take advantage of Hyper-Threading technology. While many programs can benefit from Hyper-Threading technology, some programs have not
been optimized for Hyper-Threading and may require an update from the software manufacturer. Contact the software manufacturer for updates and
information on using your software with Hyper-Threading.
NOTE: Hyper-Threading is supported only on computers that have 3.06-GHz (or higher) microprocessors installed.
To determine if your computer is using Hyper-Threading technology:
1. Click the Start button, right-click My Computer, and then click Properties.
2. Click Hardware and click Device Manager.
3. In the Device Manager window, click the plus (+) sign next to the processor type. If Hyper-Threading is enabled, the processor is listed twice.
You can enable or disable Hyper-Threading through
