In a previous article, I talked a little bit about Magento full-page cache (FPC), how it behaves and functions, and how to overcome some of the nuances you get when enabling it. It’s no question that full-page caching is crucial to any Magento store under high traffic and ultimately, focusing on getting it to work should be top priority for optimizing any Magento store.

This tutorial series is going to build upon some of the topics discussed earlier and touch on other popular ways to speed up Magento – I hope to cover topics such as block caching, indexing, and server caching theories. In this article we’re going to cover what flat tables are and how to use them in an existing Magento store.
