If this is representative of the usual state of your machine, then it seems
indeed a very stressed one. I usually get load averages of 0.17, 0.17, 0.15
on my AMD 300MHz with 384 MB RAM, and I'm running a slew of server software.

Hmm... too many top instances, and it seems you've caught sendmail on its
occasional busy moments.
The 'top picture' taken above was taken 35 minutes after boot, perhaps the
machine is still running the daily/weekly/monthly anacron jobs? Make sure
you understand the way your system runs in as much detail as possible.
- do an occasional 'ps', and try to understand what each entry is doing
there
- check your /var/log/ files, especially syslog and messages.
- check /etc/anacrontab and all /etc/cron* items
