I hope this article has given you some ideas on how to measure your application's heap usage from build to build, plus a few handy techniques for finding and fixing leaks when they inevitably occur.

You should, however, fix the nursery size at a large value to minimise time spent in garbage collection, and enable the tenured heap to resize itself according to occupancy to build in resilience.

Even if you don't do much with the heap dumps at first, collecting them from build to build is invaluable when you do need to make use of them.
