I encountered some server lags on my world (alone or with three online) and wondered, why 5,7GB of my 6GB of RAM were used.
So I started Spark to see what's going on.

And I guess the "BlockPosFunctions.getNearbyVillage()" is yours? ;)

It uses 33,39% of all Ticks or rescources? Don't know exactly but it is one thing I encountered to be the most demanding process I guess....

Full path:

Or am I completely wrong here?
