This library contains Java code for several Read-Write Locks:
- ScalableRWLock: A rw-lock that scales with the number of threads doing read-lock.
- ScalableRWLockS: Similar to above but different implementation.
- ScalableStampedRWLock: An hybrid of the ScalableRWLock and the StampedLock provided in JDK 8, which provides good overall performance.
- FAARWLock: Uses a Fetch-And-Add operation for the read-lock which means it is not so scalable as ScalableRWLock but it is still faster than classical implementations
