Another option is to compare a minimally optimizing compiler with a more optimizing compiler. This one can do in Java land with client/server flags. Client takes for our workload 15% more time to run than server. Now what is that 15% worth? Take the new AMD Epyc to go from 2Ghz to 2.2Ghz is worth 800USD (3200->4000). That means running JVM -server gives a value at that level of about 1/3 of the server CPU cost over running the same JVM -client. Of course that is at the top level and would be less in the middle.
