You may speed up Windows XP if you optimize windows XP system cache settings at LargeSystemCache in Windows registry. According to the Microsoft you can determine whether the system maintains a standard size or a large size file system cache and how often the system writes changed pages to disk. Increasing the size of the file system cache generally improves system performance, but it also reduces the physical memory space available to applications and services. Similarly, writing system data less frequently minimizes use of the disk subsystem, but the changed pages occupy memory that might otherwise be used by applications. System cache mode is designed for use with Windows server products that act as servers. System cache mode is also designed for limited use with Windows XP, when you use Windows XP as a file server. This mode is not designed for everyday desktop use. If you use a server product as a desktop, you should consider changing the resource allocation to Programs mode or adding more physical RAM.
According to the Microsoft when you enable System cache mode on a computer that uses Unified Memory Architecture (UMA) based video hardware or an Accelerated Graphics Port (AGP), you may experience a severe and random decrease in performance. For example, this decrease in performance can include very slow system performance, stop errors, an inability to start the computer, devices or applications that do not load, and system instability.
In Windows registry use this to modify LargeSystemCache values:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
Double click at the LargeSystemCache and change the value to 1.
Value 0 = Programs, establishes a standard size file-system cache of approximately 8 MB.
Value 1 = System Cache, establishes a large system cache working set that can expand to physical memory.
Instead of manualy edit the Windows registry use this Windows XP trick to change the system cache settings: Optimize Windows memory usage for faster memory management.
