As stated in the text, the chart shows the ratio of the MP effect between the 2 z/VM releases using z/VM 5.3 on 6 CPU's as the baseline. For up to 6 CPU's the conclusion would be that both releases perform reasonably similarly. To determine the magnitude of the MP effect at 6 CPU's would require running a test with 1 CPU and comparing the ITR ratios to see how close t o a 6:1 ratio they are. Brian Nielsen
