Is this normal for CPU usage on a VPS that has two small (wp) sites on it?

No. What kind of cpu do you have there?

Check 'top' and look to see which processes are using the cpu. Check especially the "Nice" processes which I think should have a nonzero value under the "NI" column. There is something strange there and that looks to be using most of your cpu. It's "nice" (see https://en.wikipedia.org/wiki/Nice_%28Unix%29 ) but even so if you don't know what it is then it might be a problem.

Do you know the command to see what is running "nice"

$ top

last pid: 86695; load averages: 1.07, 1.06, 1.05 up 43+08:26:19 20:08:19
4 processes: 1 running, 1 sleeping, 2 stopped
CPU: 2.3% user,
77.8% nice,
19.2% system,
0.8% interrupt,
0.0% idle
Mem: 108M Active, 104M Inact, 132M Wired, 22M Cache, 60M Buf, 118M Free
Swap: 1001M Total, 115M Used, 886M Free, 11% Inuse

When you run 'top' It should show a bunch of header information as you typed but then also a bunch of processes under that and this should update every second or two.. There should be a column labeled "NI". On one of my servers it is between "PR" and "VIRT". Check that column for anything with other than a "0" value. Those are the "nice" processes. A positive value means lower priority whereas a negative value means higher priority. By default most processes are usually at the "0" priority.

Weird. None of those are the culprit although I don't know why you have so many 'top' instances. Try 'ps aux' which will show all processes. You can pipe it with 'ps aux | less' and this will let you move forward a page with <space> or back a page by hitting 'b'. See what you can find that is running.
