Now that you understand a bit more about the causes of latency-based problems, and how to analyze them, we can demonstrate some potential solutions. The measurements that you have taken using the previously illustrated tools will help you quantify the scale of the problems, and choose the appropriate fixes to be applied.
Rendering a typical web page may require calls to many different APIs (or DB tables) to gather the data required for it. Due to the style of object-oriented programming encouraged by C# (and many other languages), these API calls are often performed in series. However, if the result of one call does not affect another, then this is suboptimal, and the calls could be performed in parallel. We'll cover DB tables later in this chapter, as there are better approaches for them.
Concurrent calls can be more pertinent if you implement a microservices architecture (as opposed to the traditional monolith, or big ball of mud), and have lots of different...
