How understanding the processor architecture can help us in optimizing performance?

According to Jackie Stewart, a three-time world champion F1 driver, having an understanding of how a car works made him a better pilot.

“You don’t have to be an engineer to be be a racing driver, but you do have to have Mechanical Sympathy”

Martin Thompson (the designer of the LMAX Disruptor) applied the concept mechanical sympathy to programming. In a nutshell, understanding the underlying hardware should make us a better developer when it comes to designing algorithms, data structures, etc.

In this post, we will dig into the processor and see how understanding some of its concepts can help us when it comes to optimizing solutions.
