The iron golem is finding bells. I think the logic needs something like a cache or index

I'm seeing this as well, and it's significant. In a large village with two golems that are far from the bell, this drags an otherwise perfect 20 TPS down to 17-18TPS.

The villagers don't seem to cause the same issue, seems to be exclusively this function from the golems that causes lag.
