I'm sure Mr Gregg would chime in, were he reading this thread... but in
his absence: In Solaris 10 and above, Load Averages are now somewhat
differently calculated...
See S2.12.2 Load Averages in Solaris Performance and Tools. It says:
"The loadavg_update() function is called to add user + system + thread
wait (latency) microstate accounting times together."
Various averaging/dampening functions are then applied. This is a
change from "the average number of runnable and running threads". As
footnote 2 on page 16 (S2.6) says:
"This was the calculation, but now it has changed ... the new way often
produces values that resemble those of the old way, so the description
still has some merit."
