Memory usage, PIII vs P4 or portable vs desktop, or

Hi,

This is, I'm buttuming, not a Dell question as such, but as both machines happen to be Dells, here I am... ;-)

I have been monitoring memory usage on two PCs to gather info. re. a RAM upgrade, and found discrepancies in the amount of memory amodule takes on two PCs.

1) Dell Dimension 8300, P4 3GHz, 1GB RAM 2) Dell Labreastude CPxJ, PIII 750MHz, 512MB RAM

If I run task manager and look at the processes tab, on each machine, they show that similar processes are using different amounts of memory.

Examples avgcc.exe uses 10,860K on the Dimension, and 9,500K on the Labreastude zlclient.exe 3,196 2,820 services.exe 3,136 2,936 taskmgr.exe 4,396 3,548

avgcc.exe is part of the AVG anti-virus package and I'd buttume that it would use the same amount of memory on any machine. That buttumption is wrong, obviously, but why should that be?

Any thoughts?

Regards, John
