Sets a focus on for the most GC pause time (in milliseconds). This is the comfortable intention, and the JVM could make its ideal exertion to attain it. The specified value doesn’t adapt to the heap sizing. By default, there’s no greatest pause time price.
Autotunes RTM locking depending upon the abort ratio. This ratio is specified via the -XX:RTMAbortRatio selection. If the volume of aborted transactions exceeds the abort ratio, then the tactic that contains the lock is deoptimized and recompiled with all locks as typical locks.

) Also, for evenly contended locks that are utilized by different threads, RTM can reduce Bogus cache line sharing, also known as cache line ping-pong. This happens when numerous threads from various processors are accessing unique methods, although the sources share the same cache line. Due to this fact, the processors frequently invalidate the cache lines of other processors, which forces them to examine from main memory in place of their cache.
Sets the dimensions (in bytes) in the prefetch distance for item allocation. Memory going to be written with the value of latest objects is prefetched approximately this length ranging from the tackle of the last allotted object. Each individual Java thread has its very own allocation stage.
