10 recommended articles about jvm tuning

JVM tuning is mainly for memory management tuning, including controlling the size of each generation and GC strategy. Since GC will suspend application threads when it starts garbage collection, which seriously affects performance, the purpose of tuning is to minimize the pause time of application threads caused by GC and reduce the number of Full GCs. The most critical parameters for generation size tuning: -Xms, -Xmx, -Xmn, -XX:SurvivorRatio, -XX:MaxTenuringThreshold, -XX:PermSize, -XX:MaxPermSize-Xms, -Xmx are usually set to the same value to avoid running The JVM memory must be continuously expanded. This value determines the maximum memory that the JVM heap can use. -Xmn determines the size of the new generation space. The ratio of the three areas of the new generation Eden, S0, and S1 can be controlled by -XX:SurvivorRatio (if the value is 4, it means: Eden:S0:S1 = 4:3:3)- XX:MaxTenuringThreshold control object
