Chapter 10: Performance Optimization
Performance optimization is an endless activity. Further optimizations can always be made. The recipes in this chapter will demonstrate a typical performance optimization workflow.
The performance optimization workflow starts with establishing a baseline. Often, this involves benchmarking our application in some way. In the case of a web server, this could be measuring how many requests our server can handle per second. A baseline measure must be recorded in order for us to have evidence of any performance improvements that have been made.
Once the baseline has been determined, the next step is to identify the bottleneck. The recipes in this chapter will cover using tools such as flame graphs and memory profilers to help us identify the specific bottlenecks in an application. Using these performance tools will ensure that our optimization efforts are invested in the correct place.
Identifying a bottleneck is the first step to understanding...
