This Optimization Cycle is a practical workflow to follow step by step for this challenging task, which may lead to excellent business achievements, such as improving sales or overall customer satisfaction.

Now, you can evaluate a tracing module. By knowing how it works under the hood, you can integrate it into any application to start the measurement process. You also know which third-party software you will need to process and visualize the data, such as an APM. Moreover, you are now able to dig deeper into any performance issue, by analyzing it in detail, supported by some open source tools. Last but not least, once you have found a problem, you can plan an optimization to solve the issue and boost your application’s endpoints iteratively.

You have completed this journey toward building a performant and maintainable Fastify...
