The default benefit is ready to 500 KB. The Original code cache dimensions shouldn’t be a lot less than the program's minimum memory site dimensions. The following instance exhibits the best way to established the First code cache sizing to 32 KB:
Autotunes RTM locking with regards to the abort ratio. This ratio is specified through the -XX:RTMAbortRatio solution. If the quantity of aborted transactions exceeds the abort ratio, then the method made up of the lock is deoptimized and recompiled with all locks as usual locks.
