Follow-up...

Went from 2G to 4G RAM (of course, XP shows only 3.24G available), and after testing
reduced my swap file setting from 2G/4G to 1.5G/1.5G.

Laptop is NOTICEABLY FASTER!!! Max swap file usage never goes above 12% and is normally
at 2%. RAM usage has never gone above 56%.

Oddly enough, battery life seems to be improved?!?!?!? It must be that accessing the
extra RAM is more efficient than hard disk usage for the swap file - never thought of
that!

I can easily believe that operating the disk takes more juice than
reading/writing RAM.
