Mob spawning, Performance
MC-134696 but I was told to create a new issue.
Cods can rapidly spawn and despawn. They don't respect their cap. This can cause 400+ cods to spawn, dropping the server performance.
This happens more regularly when moving into unloaded chunks, but this is not always required. After a minute the numbers go back down. I printed the number of cods in chat every 10 seconds and attached a screenshot with the results.
How to reproduce
- Load chunks near an ocean where cods spawn.
- Cods should start spawning immediately.
- /execute if entity @e[type=cod] shows how many cods are loaded. In my testing this could be as high as 500 entities.
- Notice the server performance has dropped significantly.
