The Missing Benchmark Metric: Memory Consumption

[Jens Wilke]

Title:
The Missing Benchmark Metric: Memory Consumption

Abstract:
When doing benchmarks we are usually interested in comparing the throughput of 
different solutions. However, when the code under investigation is not 
trivial, memory consumption may vary significantly, because using more memory 
to achieve better throughput is a typical design trade off.

The talk discusses what memory metrics are more or less meaningful and what 
approaches can be used to track memory consumption alongside JMH benchmarks. A 
special focus will be given on dynamic effects on the interaction with the 
garbage collector and whether it is possible to get some stable benchmark 
results.

Remark:
The talk is based on a blog article which was well received in the Java 
performance community. I'll plan to present some updated results for the 
latest JVM and GC implementation. Link:
