How do you deal with entities?

Hi,
I have a nice server with a Intel Core i3 2130 2x2(HT)x3.4, 16Gb de ram and my world on a ramdisk.

But my player are doing 2 things that, i think, hurt the performance:
-Animal farming:
Severals hundreds of animals in small area. This look bad for lag no?

-MobSpawner Farming:
I just broke a "mobspawner farm":

With /butcher, TPS go from 10.6 to 17.2

My server can go down to 3.0TPS with 4 players cause of this kind of farming, once the mobspawning farm destroy it goes direct to 20 TPS.

I know that mob spawning farm have great impact on performance, i'm not sure for animal farming.

How do you do on your own server? Rules to limit this? Plugins?

Thx for your help !

 

There are plugins that make it so you can't get do from mobs that came from spawners. This might take away the incentive to make those farms

 

ClearLag
NoLagg

 

Those are known to corrupt worlds

 

What about animal farming?

How do you limit them?

 

No.. stop making up random facts and clearlag Clears/Limits entities
