IO+Page+Lock+Limit


 * IO Page Lock Limit **

[HKLM\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement] "IoPageLockLimit"

//Myth// - "Increasing the IO Page Lock Limit will lock more memory for exclusive access by the kernel, improving performance."

//Reality// – "Indeed, it does do this but only in an RTM Windows 2000 machine. It does absolutely nothing in Windows 2000 Service Pack 1 and up, and absolutely nothing in Windows XP. This makes it effectively useless, since no one in their right minds would be running RTM Windows 2000. The RTM kernel references IoPageLockLimit. The SP1 kernel does not. Neither do any subsequent editions of the kernel; neither does the XP kernel in any of its incarnations."
