In this chapter, we will dig deeper into performance considerations when you are building Lightning Components. We will explore the concept of stored actions, which are caching mechanisms available to cache a dataset to improve its performance. We will also learn how to design your backend Apex code to improve performance.

We will explore how tags such as aura:if used inside aura:iteration within a large dataset can cause rendering issues. We will look into strategies to keep the number of components to a minimum to improve load and rendering time. We will also look into some Lightning base components that can reduce work and code complexity and can add significant performance improvements.

In this chapter, we will explore the following topics: 

• Storable actions
• Lightning Component tags that can cause performance issues
• The benefits of lazy loading using $A.createComponent()
• Events architecture for improving performance
• Server-side Apex optimization for performance improvements
