your System Memory
Updated on July 18, 2000 by Thomas
of, the more RAM you have the better, 128MB
RAM is ideally the minimum of what anyone running Windows
2000 should have. This OS, much unlike Windows 9x has far
better Memory management, one reason for this is because its
meant to, Windows 2000 is intended for business/server use,
not as a desktop system. Windows 2000 also uses a Paging file,
which for all intents & purposes is the exact same as swap
file in Windows 9x, just a different name (pagefile.sys) &
a few other subtle differences.
you have below 128MB RAM or less then you really should buy
more RAM. This would be of far greater benefit to you than
anything else. Much like the Windows 2000 Services guide this
one goes into detail regarding settings & such, although
if you're like me it's nice to know why
& what you are
doing. This is also probably the most comprehensive/definitive
Windows 2000 memory guide around in terms of topics, settings
& definitions covered. With that, on with the guide.
IMPORTANT NOTE – You must
be logged in as an Administrator
to make (most) changes to these settings. So log on as one if
you haven't already done so.
What is Virtual memory?
is a hidden file on the hard disk that Windows 2000 uses to hold parts of programs
& data files that do not fit in memory. The paging file
& physical memory, or RAM, comprise virtual memory.
Windows 2000 moves data from the paging file to memory as
needed & moves data from memory to the paging file to make
room for new data. Paging file is also called a swap file.
explanation is that it is, temporary
storage used by a computer to run programs that need more
memory than it has. For example, programs could have access to
4 gigabytes of virtual memory on a computer's hard drive, even
if the computer has only 32 megabytes of RAM. The program data
that does not currently fit in the computer's memory is saved
into paging files.
it is generally more efficient to set this yourself rather
than let Windows 2000 manage it (Although Windows 2000 does
much better Memory management than Windows 9x does).
Hard drive setup
you may know, the Page file exists on your hard drive(s),
which is much slower than using RAM. So speeding up your hard
drive can improve Page file performance a lot. Although more
RAM is highly recommended, having fast hard drive will
My Computer, right click on the hard drive(s), select Properties. Select the Hardware
tab. Now highlight the desired hard drive & click the Properties button. Finally, select the Disk Properties tab & SCSI
Properties, where applicable. The following options can
improve Hard drive performance. NOTE
- Some of those options may, or may not be available depending
on hard drive type, e.g. SCSI or IDE.
Write cache enabled: If you enable
this feature, your computer sends an enable-write-cache
command to the hard disk activating the hard disk write-back
cache, & if you disable
this feature, the hard disk write-back cache is deactivated.
When enabled disk I/O performance may improve, although if you
experience system failure e.g. Power loss, you could
experience drive/file corruption. I'd recommend leaving this ticked unless your system is prone to bad shutdowns/power failure.
Disable Tagged Queuing:
Tagged queuing is done by the SCSI controller & driver to increase
the speed of completing I/O tasks. This is accomplished by
sorting the commands so the order of the commands issued to
the physical disk drive to read or write results in the most
efficient movement of the physical read & write heads.
As you can guess, doing it in this sequential order is far
more efficient than when disabled, resulting in greater I/O
performance. You should only
tick this if you are experiencing problems with a hard drive(s)
as performance is slower when Tagged queuing is Disabled.
Leave it unticked.
