Changing Registry to use 64 bit WIndows better

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\Contr ol\
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

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.

YMMV

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.

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.

See comments above.

The keys would work in both, but note that the 32-bit editions of
Windows 7 don't use memory above 4GB anyway.

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.
