- It's been a few days since I enabled the G1GC on DSpace Test and the JVM graph definitely changed:
![Tomcat G1GC](/cgspace-notes/2017/11/tomcat-jvm-g1gc.png)
## 2017-11-20
- I found [an article about JVM tuning](https://www.cakesolutions.net/teamblogs/low-pause-gc-on-the-jvm) that gives some pointers how to enable logging and tools to analyze logs for you
- Also notes on [rotating GC logs](https://blog.gceasy.io/2016/11/15/rotating-gc-log-files/)
- I decided to switch DSpace Test back to the CMS garbage collector because it is designed for low pauses and high throughput (like G1GC!) and because we haven't even tried to monitor or tune it
