So i am running a survival server, with around 10 people the TPS would drop quite alot to around 10-14 but when i clear all the monsters (/killall monsters) TPS slowly goes back to 20. i uploaded a picture of my server stats, thats after i've cleared the monsters. My question here is is there a plugin or setting i can change so there are not too many monsters that causes lag. And there are also alot of passive mobs that i cant clear right now because of people's farm. (peopl can only have 35 animals) And if there is anything i can do against the amount of chunks loaded and spawners active which seem to be alot to me. Thanks in advanced!
