A slow removable storage device may be very slow to respond when multiple read and write operations are performed against the device in Windows Server 2003 or in Windows XP x64 Edition

Consider the following scenario:
  • You connect a relatively slow removable storage device to a Microsoft Windows Server 2003-based computer or to a Microsoft Windows x64-based computer. For example, this device might be a Magneto-Optical (MO) drive, a compact flash memory device, a USB 1.1 flash memory device, or some other similarly slow device.
  • In Device Manager, you set the write cache policy to Optimize for performance on the Properties dialog box.

In this scenario, the operation may take a long time to finish.
64-bit versions of Windows do not support 16-bit components, 16-bit processes, or 16-bit applications

The x64-based versions of the Microsoft Windows Server 2003 operating systems and Microsoft Windows XP Professional x64 Edition do not support 16-bit programs, 16-bit processes, or 16-bit components. However, these 64-bit versions of Windows may recognize some 16-bit installers and automatically convert the 16-bit installer to a 32-bit installer.

Note: The only solution this article proposes for running 16-bit components is to dual boot with a 32-bit XP on a separate disk volume or separate physical hard disk, which is a bit of stretch considering that the free Virtual PC 2007 supports 64-bit hosts.
Programs that use the QueryPerformanceCounter function may perform poorly in Windows Server 2003 and in Windows XP

In Microsoft Windows Server 2003 and in Microsoft Windows XP, a program that uses the QueryPerformanceCounter function to query system time may perform poorly. For example, if you run the ping command at the command prompt, you may receive low or incorrect latency values.

This problem occurs on computers that are running an x64-based version of Windows or an x86-based (32-bit) version of Windows.

This problem occurs when the computer has the AMD Cool'n'Quiet technology enabled in the BIOS.

How to determine the appropriate page file size for 64-bit versions of Windows Server 2003 or Windows XP

The 64-bit versions of Microsoft Windows Server 2003 and Microsoft Windows XP can support more RAM than the 32-bit versions of these products. When lots of memory is added to a computer, a paging file may not be required. When you use the Pages/sec counter to measure paging file use, the value that is returned may not be accurate. To obtain an accurate measurement of paging file use, you must also use other performance counters. You can use System Monitor measurements to calculate the size of the paging file that your computer requires.

Windows Server 2003 Domain Controllers are not supported without a configured pagefile. Because the algorithm the LSASS database cache depends on the "transition pages repurposed/second" perfmon counter, a pagefile is required to make sure that the database cache is capable to release memory if memory is requested by other services or applications.
