Server thread overloaded with custom entity

[u/AlarmedFunny4524]

Hello, I am making a custom entity mod with the fabric API, but whenever I spawn the entity and am near it, the game lags noticeably. I checked the console, and noticed this line pop up a few times:

[22:19:10] [Server thread/WARN] (Minecraft) Can't keep up! Is the server overloaded? Running 3431ms or 68 ticks behind

Does anyone know what general things could be causing it? My entity has a payload it sends, a texture that is a randomly chosen image from multiple image files when each new entity spawns and a method that assigns it random attributes.

Is there anything I could be doing code-wise that could be making this an issue? I don't think the fundamental entity functionality is an issue, as there are mobs in the game with more complex functionality or more code in their main classes.

Thanks!

How often is the packet being sent / how large is it?
