We have a 3800 CPW 550-7154 Standard edition. It has three active
LPARs, all uncapped and our production LPAR averages around 60% cpu with
peaks up to about 150%. It appear to be able to go to 280% but I've
never seen it go much above 200%. Our nightly cycle is mostly a single
threaded program stream.
We have received a code for temporary activation of the CUoD and would
like to try it out, the question is, will this help us at all? The
system does not appear to be constrained by CPU, memory(24 GB main
storage) or I/O (avg arm utilization about 4% on 48 mirrored drives.)
Our databases keep growing and we need to shorten the nightly cycle
time, especially at month end.
