Changing Registry to use 64 bit WIndows better
in [64 Bits Windows]
|
From: Turtle on 1 Aug 2010 06:23 Hi everyone, I have a Windows 7 64 bit Version with 6 GB RAM. In a PC Magazine I read if one has more than 2 GB RAM one can change the registry to use this memory better. REGEDIT: HKEY__LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ Session Manager\Memory Management Double click DisablePagingExecutive and change Value from 0 to 1. Change LargeSystemCache Value from 0 to 1. This should come into effect after booting new. Windows loads in the memory and not on the Hard disk. Does anybody agree or disagree with this? Does it matter whether one has the Windows 7 64 bit Version or the 32 bit version? Thanks in advance for your help. John
From: mikeyhsd on 1 Aug 2010 07:56 take a look at Task Manager Performance, write down the memory figures make the change, making note of the original values check Task Manager Performance again compare against the original. if it appears that more OS is in memory then the change may help you with a few microseconds. mikeyshd "Turtle" <mhauserj(a)googlemail.com> wrote in message news:31ed1$4c554b30$6d5a1439$16198(a)news1.surfino.com...

Leave it alone. Even *if* it gave you a performance boost (most of those tips have been around since at least Windows XP) it would be a small one (seconds of saved time *every year* maybe; YAY!) and could cause some instabilty (what - why did the system freeze? what does this bluescreen mean?) Not worth it. Leave it alone - set the system to let Windows manage the Page File and go. If it does not perform to your needs - you made an unwise purchase and need to consider a processor/memory/video device upgrade.

This affects the Kernel Executive, a small part of the OS kernel. The number of occasions on which Windows might page out this bit of the OS on a 4+ GB system are so few that the possible performance benefits are minuscule. > Change LargeSystemCache Value from 0 to 1.

For desktop machines, you want Applications; for servers, you want Background Processes. So flipping this key may actually *negatively* affect performance of a desktop machine. > This should come into effect after booting new. > > Windows loads in the memory and not on the Hard disk. > > Does anybody agree or disagree with this?

The keys would work in both, but note that the 32-bit editions of Windows 7 don't use memory above 4GB anyway. -- Steve Foster For SSL Certificates, Domains, etc, visit.: https://netshop.virtual-isp.net

No, this (LargeSystemCache) favours memory usage for file caching rather than running applications. Enabling the LargeSystemCache allows the system cache to expand and use all but 4MB of the physical memory, good for busy file servers... not so good for workstations. John
