max-entity-collisions doesn't work anymore (HUGE lag!)

[Platinteufel]

Hey,

I'm running a survival server with about 50 players online. The new entity-collision-system is eating my CPU, I'm not able to run my server with more then 12 TPS atm.

I've just tested it with about 450 chicken in a small hole.

TPS in 1.8: 19.7
TPS in 1.9: 8.67
Specs: E3-1271v3, Java 8 64 Bit, latest Paper

Timings:
Paper 1.9: http://timings.aikar.co/v2/?id=066e2411eb4f4bfaba252a5daf89a3b8
Spigot 1.9: http://timings.aikar.co/?url=15331416

94.85% 218.33% 86.34 s 109.16 ms 369 291.9k tickEntity - EntityChicken
72.03% 165.77% 65.56 s 82.89 ms 377 298.1k livingEntityAICollision

I've set max-entity-collisions to 0 and it didn't change anything. I'm not able to run my run my survival server smooth anymore. :/ A fast fix would be awesome!

Appears to have been fixed in Spigot just a short while ago
