Since 10.04, we add more features, and it probably takes more ressources
than expected. For example, we "lost" 10 Mb of RAM for update-notifier,
which warn about crashes and updates. We try to minimize this impact,
but sometimes we can't avoid this.

About CPU usage, there is a bug in the theme, which cause more CPU usage
than expected (see
https://bugs.launchpad.net/ubuntu/+source/lubuntu-artwork/+bug/776776)
You can try to use the LXDesign theme in the meantime, the CPU usage
should go back to the normal.
