How you can improve system performance is about determining where the
bottleneck is. RAM memory is just one aspect. CPU processing capacity,
disk read / write speeds etc are others. It can even get down to
avoiding multi-tasking and timing automatic scans at more convenient
time. In essence it is the balancing of supply and demand. Cutting out
wasteful use of memory is as important as ensuring you have enough RAM
to carry the tasks you require your computer to perform.
To determine how much RAM is needed you should not look at what RAM is
being used but what use is being made of virtual memory (the pagefile).
In simple terms you can look in Task Manager at the Commit Charge figure
on the Performance tab. Deduct the amount of installed RAM from the
Total and you get a rough idea of how much the pagefile is being used.
If the figure is negative then very little use of the pagefile is
currently is occurring (the system and some programs make some use of
the pagefile notwithstanding the existence of available RAM memory). Do
the the same exercise with the Peak to see what has been the situation
previously. Normally you need to think of adding RAM if you are seeing
pagefile usage above 10% to 20% of the installed RAM.

You can get more accurate information on pagefile usage using
pagefilemon, a small freeware utility.
Use page file monitor to observe what is the peak usage. Start it to run
immediately after start-up and look at the log. Pagefilemon takes
snapshots. You need to run it at the beginning of the session at then
run it again at intervals throughout the sessions. The log is Pagefile
log.txt. If you right click on the file in Windows Explorer and select
Send to, Desktop (Create Shortcut). The same applies to
XP_PageFileMon.exe.
A small utility to monitor pagefile usage:

Note that programs using undo features, particularly those associated
with graphics and photo editing, require large amounts of memory so if
you use this type of programme check these first observing how the page
usage increases when they start and whether the usage decreases when you
close the programme.
