Benchmarking Functional HTTP Services in Scala

Choosing the right architecture for your web services is critical, but understanding the actual performance trade-offs between pure functional programming and traditional imperative approaches can be challenging. This text-based course guides you through the process of setting up, executing, and analyzing performance benchmarks for Scala HTTP services. You will learn how to gather empirical data to make informed architectural decisions. What you'll learn: Understand the core differences between pure functional and impure Scala HTTP frameworks; Configure Apache JMeter to simulate realistic concurrent traffic loads; Measure key performance indicators including latency, throughput, and resource utilization; Analyze garbage collection behavior and memory allocation patterns in the JVM; Apply modern benchmarking best practices to isolate variables and ensure reproducible results. The course begins with foundational definitions of purity, side effects, and JVM performance characteristics, before moving into step-by-step benchmarking setups and data analysis. This course is designed for backend developers and JVM engineers who are new to performance testing or functional Scala and want to learn how to quantify application efficiency.
