Notable lag with Ice&Fire mob multipart

[Krutoy242]

Describe the bug

I have two dragons on a server. They standing on the mountain and do nothing.

Yet, i could see that they causing about 4% of server lag. Narrowing down Spark profile I could see that it ended up with FluidloggedAPI calls

Additional context
Happening on modpack E2E-E

Is it normal that idle dragons consume so much CPU? Is there options of FluidloggedAPI that could decrease this lag?

Update:

Same happens on Fluidlogged-API-v2.2.7 too https://spark.lucko.me/RTBKVibM7A
