It’s a given that anything that runs in RAM will be faster than an item that has to
access the hard drive and virtual memory. Rather than have the kernel that is the
foundation of XP using the slower Paging Executive functions, use this hack to create
and set the DisablePagingExecutive DWORD to a value of 1. Perform this hack
only if the system has 256MB or more of installed RAM! Edit the Registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\
Memory Management\DisablePagingExecutive to 1 to disable paging and have the
kernel run in RAM (set the value to 0 to undo this hack). Exit the Registry and reboot.
