Introduction
Different Mutex solutions and Overheads
Software Overhead
Reducing the overhead - solutions
Thick locks
Thin locks
Language supported synchronization leads to inefficiency due to the useless synchronization requirements due to the thread safe nature of the Java Libraries. The necessity of locking introduces the use of heavy weight objects. This problem is solved by using a new algorithm that requires fewer machine instructions and lesser number of bits per lock.
