What are the ArcInfo Workstation performance issues on Microsoft Windows XP and Microsoft Windows 2003 Server?
ArcInfo Workstation users may experience decreased performance when running Windows XP Service Pack 2 on computers equipped with multiple processors that support processor power management features, such as Advanced Configuration and Power Interface (ACPI) processor performance states.
This problem also applies to x64-based versions of Microsoft Windows Server 2003.
Without these updates, computers that are equipped with these power management-capable, mobile, dual-core processors may experience decreased performance or unexpected behavior.
Microsoft has identified the performance problem with these dual-core machines and has provided a Web site that describes the problem and offers an update to fix the problem. This fix is designed for Windows XP and Windows 2003 Server.
To download the update, go to: Microsoft Help and Support KB896256
A Windows fix for Vista has not yet been published.
