load average - what do you mean?
The paging space # of 2.4% does not really mean much, because you have too much paging space to begin with. You can just turn them off the two extra ones with the swapoff command (and perhaps later rmps to remove them permanently).
vpundit: I was not aware that the rest of UNIX had caught up with AIX - and using memory for file cacheing - good to hear.
regarding the ratio of entitled capacity to virtual processors: your ratio of 1:10, while legal is not considered best practice. as mentioned "xRay" paying attention to SRAD information is important.
use the mpstat command to see if you are using a single thread on each processor - if so, count the actual processors being activated, divide that number in two and use that as your number of VP - that should lower your physical processor cost.
lparstat output is important to see "app" value - as an estimate of how busy the system as whole is busy.
but in all honesty, there is so much that needs to be done, it is all patchwork until some proper settings are applied, and all testing restarted.
