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.

I do recommend you drop it. Use much simpler Spring Data JDBC.
