Java Virtual Machine (JVM) Performance Tuning Tutorial
Summary
For instance, if an app has a badly designed architecture or poorly written code, you can’t expect performance to skyrocket by merely tuning the JVM. Either way, the goal of JVM tuning is to optimize the garbage collector so that you have high throughput with less memory consumption and low latency. That said, tuning is a lengthy process where you’ll more than likely perform ongoing configuration optimizations and multiple iterations based on the stress and benchmark tests results. In the final step of JVM performance tuning, we run throughput tests on the results we got so far and then make slight adjustments if needed. For a garbage collection, throughput tuning has two purposes: to minimize the number of objects passed to the old area and decrease Full GC execution time or Stop-the-World events.
