How does it compare to say, sar -P ALL 1 in terms of %idle?

Anyone else running AIX 5.3ml3 seeing load numbers coming form uptime, to
be less useful than the mpstat runque numbers?

*uptime reports -*

 09:06AM   up 2 days,  14:51,  56 users,  load average: 41.50, 34.30,
29.37

I am not seeing any of the slowness I would expect from this kind of load
so I have spent the last couple of days with snapshots trying to figure it
out just what is going wrong.

I don't know but I suspect that the problems with the utmp and wtmp files
are causing finger issues

The performance and processes are much more in line with mpstat run queue
numbers than with uptime run able process numbers.
