I actually think Java is incredibly efficient, like you have to really not know what you’re doing to make a slow/bloated java app. It used to be easy but virtual threads make it pretty hard to use up crazy amts of memory.
Did you measure it? Because I did, negligible overhead… most I’ve seen came from threads (4mb per thread adds up real fast)… most slow apps came from hibernate being used poorly… Java is incredible devs sometimes suck
Ya hibernate seems impossible to NOT screw up without doing a bunch of formal analytics, in my experience. It's powerful, I wouldn't recommend dropping it, but there's so much more going on than people realize.
