Changing the weight from 65 to 75 (in your particular environment) increased the available MIPS to the PROD LPAR by 15%: (75-65)/65=15.3%
Another simple example: if you have 1000 MIPS, your Prod LPAR went from 650 to 750 MIPS, which is not an insignificant change. Conversely, the test LPAR went from 350 to 250 MIPS. If you are not capping, both LPARs have access to MIPS that the other LPAR is not using. The weights come into play when things get busy. You can measure this by comparing things like TSO performance, batch turnaround times, online response time, and by how loud the complaints are (if any). MXG will give you info on all of that except for the complaints. For those you're on your own.....

What reports would help me see if this is doing any good? I have MXG and SAS. I can also run RMFPP. I have not really gotten into performance tuning on this level so I need to try and find the reports that will help me understand this picture better.
