Full GC in JVM is crucial for memory management but can severely impact application performance due to high CPU consumption and application thread pauses. Consecutive full GCs typically indicate insufficient heap size allocation. Solutions include increasing JVM heap size, enhancing Perm Gen/metaspace size, or adding more JVM instances. Validation is essential.
In Java 9, G1 GC will become the default garbage collector. One of the key features of G1 Garbage collector is its ability to limit the GC pause time (i.e. you can set the desired maximum pause time) without compromising on throughput.
