English session - Intermediate
I once wrote a program to demonstrate the performance of different Java collections to my students. The differences between the collections were what I expected but the values changed significantly for each run. Then I discovered the Java Microbenchmark Harness or JMH. Think of it as unit testing for performance rather than correctness. In this presentation I will talk about the original performance program and the enhanced version using JMH.
