Are your G1GC Logs Speaking to you?

In this session we will look at the G1GC logging to learn how to use the data to improve application performance while reducing hardware footprint. The G1GC has come a long way since it was first supported in Java 7 update 4. At that time is was very difficult if not impossible to obtain results that came close to those obtainable with the mostly concurrent mark sweep collector. Now it is possible that the G1GC will perform as well if not better than CMS with minimal or no tuning at all. However there are still conditions when a little bit of hand tuning is needed which means you’ll need to be able to understand what the G1GC logs are telling you.
