How CyBench code benchmarks can help measure GC memory overhead across releases in an open source Java logging framework — TNT4J.
The case study details benchmarks across multiple TNT4J releases. We benchmarked TNT4J framework (which is available in https://github.com/Nastel/TNT4J). TNT4J is a logging framework for tracking and tracing applications, activities, transactions, behavior and performance via a Java API. This benchmark shows how later version of TNT4J measures in terms of throughput and GC memory overhead.
