Estimating how much memory your server is consuming on average.. best way to do so?

We run server 2003.. x86, x64 versions..

What i frequently do is check the total used memory just after a boot
is completely done...

Often times as an example.. I find this value for instance:


1200mb used (out of say 2000mb)...

Ill let the system run for days.. maybe 2 weeks later.. I check this
value.. and it is at say.. 2400 out of 2000 (meaning its using the
paging file)...

An example of things on this server might be SQL 2000 instances (say 3
of them), Sharepoint, some other services, sourcesafe..

Does a rule of thumb of just doubling that initial startup used
memory.. sound like a reasonable gauge for how much memory the system
will need in the long run?

IE: so this system would be better suited with 3gb or 4gb of memory.


**Side question: does anyone how much bigger the base memory
footprint of server 2008 will be, compared to 2003? IE: 512mb?

Thanks
