This ratio is employed when the -XX:+UseRTMDeopt solution is enabled. The default price of this feature is 50. Which means the compiled code is deoptimized if 50% of all transactions are aborted.

Sets The share with the heap (0 to 50) that’s reserved like a Fake ceiling to lessen the possibility of promotion failure for your G1 collector.
