I've been discussing about how to chop up a machine.  An possible example
configuration would have 8 cpus, 3 local zones.  They would possibly be
divided up as 50%, 25% and 25%.  Its clear how to do this with pools,
however FSS is a great fit for when a zone may need more CPU than whats
available in the pool/psrset.  The problem with FSS in this case is that
if one zone is mostly idle and all the other zones are busy, the zone
that is idle will get a load average much higher than its really using
which can skew the calculations use by the sendmail process to determine
if the queue/refuse connection thresholds are met.

How does FSS make that situation worse? The misleading [1] load avg is not affected by FSS, which is merely enforcing the minimum CPU-power portions that you chose. If they are inappropriate, prctl can be your friend. :-)


[1] "misleading" for this situation, not so for others.
