Symptom
· A very high proportion of the working memory is occupied by DATA Boreum.
Cause
· In the default setting, the JVM performs a memory clean-up in the application relatively rarely. The added parameter XX:+UseZGC helps to prevent a high load in the working memory. Further optimization can be achieved via the Java variable XX:ConcGCThreads. We recommend specifying a number that is smaller than the number of processors, otherwise clean-up work can hinder the application. For example, with 8 processors, configure a number from 2 to 7 processors, e.g.:
XX:ConcGCThreads=4
