SP2 breaks custom paging file size-my system is dog slow

Since I installed SP2 on two of my computers, they have been running (old)
dog slow.

I think I have tracked this down to the custom paging file size.
I normally run with 2Gb of page file (2048MB).
I have administrator privileges.

The Performance Options-Advanced-Virtual Memory dialog box shows my custom
size as having been entered and accepted,
but on Performance Options-Advanced it stills shows the current page file
size as being the system chosen value of 767MB.

I also noticed on the Defragmentation dialog, my unmovable sysem file has
shrunk dramatically.

Is this a bug, or is there something else that I should be doing?

XP will ALWAYS set the maximum page file to equal the installed ram size
plus half the installed ram size(1.5 times the size of installed ram). So if
you have 512Mb ram it sets it as 512+256=768Mb.

Why would you you set it to 2Gb? XP will never use it and you're locking up
2Gb of your Hard drive that way. I would suggest going the other way and
*reducing* the size of the pagefile, to make XP and your running
applications utilse the avialable ram. I have my page file set at minimum
256Mb and Maximum also 256Mb, but then I have 1.3Gb ram in this computer.

Some references on optimising ram useage and the page file in XP:

PS. There are a lot of [often conflicting] opinions about the page file, how
big it should be, how to use it effectively, where it should be located,
etc.....
