I was wondering about another thing... In most youtube videos and screenhots here and there I see people having a multiplayer chunk cache of around 425 or something. However, mine on my local server is pretty rediculously high at 625.. I sometimes see spikes on chunk updates to 4000!!! No idea why as the only few chunk loaders (dimensional anchors) I have only chunkload a small area.
Is there any way to bring that MP chunk limit down since I think that might also speed up things?
