That snapshot shows a few points of note:
- You have no swap. That's OK, but personally I like some swap, just in case
- The machine isn't using all its RAM yet, but that's OK because it was booted only 21 minutes ago.
- The daemon for
updatedb
is running (PID 2792): that's what's causing all your disk activity.updatedb
is what helps thelocate
command to find things quickly. It is very busy, but should finish in a couple of hours.
I hope that helps
