@rhtyd Good to see change in the GC for management server process. Even though Parallel GC is the fastest, there are some side effects of using Parallel GC. - Parallel GC is the default GC in Java 8, which is changed to G1 from Java 9 [1], due to higher GC pauses. - All application threads are stopped during GC, can impact response time / latency. Check some use cases for Parallel GC here [2]. [1] http://openjdk.java.net/jeps/248 [2] https://www.informit.com/articles/article.aspx?p=2496621&seqNum=2 I think, it is better to control such pause times using option "-XX:MaxGCPauseMillis", when we opt for Parallel GC. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
