Something like running jbb2015 and other benchmarks without any options
(maybe just max heap), and looking at if there is any change in for
example heap/generation sizing or when we start concurrent cycles.
It's probably also good to look at the logs for a tuned run and see that
things looks the same there, but when tuning the heuristics don't get as
much room.

I agree with you, I guess it can be done as a follow up.
