Since I upgraded my ibook from 512MiB to 1.25GiB, i live in a new world. I should have upgraded earlier to put an end to my nightmare.

User memory usage is now 450MiB so the kernel/disk/buffer cache is big and makes my system faster than ever :)

Back when i had only 512MiB, i used to have 300MiB of swap usage :

  • the switch between evolution mailer and calendar used to take 15s. It's now 3s !
  • starting a new terminal now only takes 1s where it lasted up to 10s !
  • the gnome-menu is totally new to me : it's fast ! it instantly popups where it used to trash my disk for 3s before opening.
  • etc, etc

You can't really understand memory issues if you don't run a computer with <= 512MiB. So boot your computer with mem=256M and enjoy
