I don't think that loadaverages have any objective interpretation.
A .36 does not mean that you are using 36 percent of anything, it just
means that if recent past is a good indication of the future, then
in the next 100 seconds, you might expect 36 processes to get the CPU.
(They might not hold it for very long; perhaps they will wake up on
a socket they were waiting on, collect 1 byte of data, and go back
to sleep for more data.)
There would probably be a hue and cry if loadaverages were removed
from the system, though you need to know how the whole system behaves
w.r.t. loadaverages before you make any interpretation of what is a
"high" load.
That, at least, has been my understanding. I wouldn't fret about
those numbers without more context. (^&
