It's running with an average of 50% idle or so but the load average is
kinda high:

170 processes: 164 sleeping, 1 zombie, 1 stopped, 4 on cpu

FWIW, that load average is not "kinda high". You've got 8 cpus and only 4 jobs on a cpu - that means you've got 4 cpus doing nothing which also explains your 50% idle time. You are not CPU bound. You also don't seem to be memory bound.
Here's the details of a job that ran slower than I'd like. 36 minutes
from "request" to "granted". It's a high-priority backup, highest of
all of them, FWIW. It, and many of my policies now, are backing up to
storage unit groups. The AP-01 client below is an AIX media server
with NBv6.

07/09/2008 09:12:21 - granted resource ug-50.NBU_CLIENT.MAXJOBS.ap-01 Note the resource it's waiting for - it's the maximum jobs per policy (NBU_POLICY.MAXJOBS). You have it set to some number and that number has been reached. No other jobs will start for that client until a job finishes. If you check your logs, you should see that a job for that policy completed shortly before the resource was granted.
