way too big. full GC will take a couple of minutes to complete, the node essentially is unresponsive at that time. I wouldn't go over 8g for the heap . if you need more than that, you need to think about how to make your application horizontal scalable.

8G is a bit extreme, there's still difference between different generations. There are GC algorithms and options that can be tuned to fit the app profile. Generally I wouldn't go beyond 64G though.
