Saving the Failwhale: The Art of Concurrency (Page last updated December 2012, Added 2012-12-26, Author Dhanji R. Prasanna, Publisher informit). Tips:

1) Contention is unavoidable - some resources are just slower, and you must wait for them. The secrets to good concurrency are 1) ensuring that these slower resources are rarely used, and 2) during such waiting periods, giving the faster tiers other work to do so that they continue to be utilized well.
2) Overuse of synchronization constructs such as locks and mutexes leads to systems that perform poorly under load.
3) ConcurrentHashMap is an efficient thread-safe map while HashMap is not thread-safe.
4) ConcurrentHashMap doesn't do away with locks, it still uses them but it uses more than the single global lock, so that threads gain some measure of concurrency. It uses separate locks for partitions, so that multiple threads writing to the map are likely to access different partitions, using separate locks and therefore process their data simultaneously. This technique is known as lock-striping. Efficient striping uses a number of locks proportional to the number of CPU cores in a system.
5) The asynchronous processing model smooths resource spikes by adding requests to a queue which is serviced by a pool of workers - spikes in requests make the queue grow rather than overloading the workers. (The ExecutorService is essentially a thread pool accompanied by a task queue.)

No shared operational state
Bound your queues
Name custom thread pools and register an UncaughtExceptionHandler
Prefer immutable data objects over mutable state

Over 50 years ago, researchers circumnavigated the Americas sampling ocean life along the way at regular intervals. In the process, they discovered a striking relationship: the abundance of a certain marine species is linked to its body size such that its collective mass is basically the same. Krill are a billion times smaller than tuna, but their numbers are a billion times more abundant. If you were to weigh all the krill in the ocean, the mass should be close to all the tuna — but not anymore. - https://www.zmescience.com[..]umans-broke-a-natural-law-of-ocean-life/
