All this memory problems make me VERY happy I have just 2 GB of RAM
in all my computers. I did this with the help of "top". I checked my
computer with 500 MB of RAM and it was using the swap file a lot! Slowed
down performance. Then I got 1 GB and that was lots better but the swap
file was still being used a little. So I upgraded to 2 GB and now the
swap file does not need to be there. It is ever used with 2 GB of RAM.
So why have 4 GB??
