RTM improves functionality for very contended locks with small conflict in the essential region (that is code that need to not be accessed by multiple thread concurrently). RTM also increases the efficiency of coarse-grain locking, which generally won't execute well in multithreaded programs. (Coarse-grain locking could be the strategy of holding locks for prolonged intervals to minimize the overhead of using and releasing locks, whilst wonderful-grained locking could be the technique of striving to accomplish utmost parallelism by locking only when essential and unlocking without delay.
