For more fundamental concepts it’s worth take a look at:

- Processor architecture: single-core vs Multi-core - Multi-Threading and its challenges

One thing I missed on this article was any reference to types of lock. A transaction created with the wrong lock can make systems become slow even when multiple instances of the application are running.
