# Memory Allocation Test
This project demos the performance and GC differences between JDK 1.8, 11, and 14. It also shows Shenandoah performance considerations.
Initial explorations are from [Logging vs Memory](https://tersesystems.com/blog/2020/07/09/logging-vs-memory/) blog post. You can read more at [Benchmarking Logging with JDK 14](https://tersesystems.com/blog/2020/08/23/benchmarking-logging-with-jdk-14/).
JDK management was done with [jabba](https://github.com/shyiko/jabba).
## Results
GC logs and Gatling results are in the results subdirectory.
