G1GC is the default GC in JDK9. As the performance engineer working on GC performance, I have witnessed G1 performance improving from jdk7/8/9. This talk will first give a brief introduction to G1GC concept and terms, then focus on identifying GC performance issues from GC logs and improving performance with G1GC tuning.

Before moving to JVM team, she worked on performance testing/improvement on various Oracle products, including WLS, Coherence, WebCenter, etc. She joined the JVM team 4 years ago, and focused on primarily GC performance.
