To keep objects few, load lazily. E.g. if you need a List<Long> of ids from a List<Thing> create a lazy list view using (some library and..) Thing::id as a map/transform function. Way faster than the Streaming API. Works better if you only work with immutable types.

I'm impressed at how much better Oracle Java performs compared to Zulu, I'd been assuming all the JDKs were fungible.

I am not seeing that? Like, vs. old versions of Zulu, sure; but the 17/18 seem about the same to me?
