The only time I would worry about memory usage is if the computer is
running dead slow and the memory is maxed out, or, if I looked and there
was almost no memory usage. Memory is much faster than hard drive reads.
If there is sufficient memory to hold all the process's running and the
computer operates fast then it's doing it's job well.
Remember back in the "good 'ol days" when most computers had 256 meg and
adding another 256 would make it MUCH faster. That was because more
could be run from memory and less from hard drive swap.
Life is what happens while you're busy making other plans.
