Hello, If you get overhead exceeded with default collector (I assume Java 8 Server class aka parallel collector) and small heaps you have a sizing or leak problem, G1 won’t help you there (it might actually make it worse).
Having said that, G1 can also be used for smaller heaps (as can be seen by it beeing default for java9+) but it isn’t that useful, as most of the GC activity should happen with stop the world new collections anyway. ParallelGC with small heaps is the easiest to use IMHO.

We want to use this GC because we are getting "GC overhead limit exceeds" and application using the default GC collector Thanks, Mohd Shaban
