Compare and Swap Operation (CAS) - Performance Tests

When doing low-latency development; we have to approach it as a science; that means:

Have a theory
Run experiments
Reach a conclusion
Write a law

Sometimes that seems to work better; does not really work better in real life.

What are we testing?

Runs a performance test on concurrency testing various implementations; like:

Synchronized
EmulatedCAS using Synchronized
Reentrant Lock
AtomicInteger

Test Results

My Test Results (best first):

AtomicInteger
ReentrantLock
Synchronized
AtomicInteger (compareAndSet)
