You are almost correct: this throughput number is defined as the ratio of
user application time to the total run time, i.e., 100% is the "ideal"

>From your reporting, ~97% is the best result so far. It's near the limit.
If you don't have a particular reason to push further, you can walk away
with your current tuning. Can you post the JVM options for your best run?

Thanks.
