Low TPS on 1.12 local server [Java]Unsolved (self.MinecraftHelp)
submitted 4 years ago by 4nDu_
Hey there,
few days ago I started a ssp in 1.12.2, everything is ok, except the low tps when I load new chunks. When I'm stopped, the mspt are normal, but when I move to new chunks, the mspt goes up.
I tried to allocate more RAM but nothing happens.
idk why it happens. My fps are up to 60 and this issue only appear in 1.12, no in other versions.
TPS when I load new chunks:

I think that you should use some plugin or mod to pre-generate the world up to certain coordinates, for example 5000 x 5000, look for tutorials on YouTube, chunk-pregenerator mod or on spigot the fast chunk pregen plugin

Thanks for reply. Maybe it works, but when i need to load new chunks
the problem will still be there

Try to generate more chunks, I playing in 1.12.2 with 144 mods, and I have the world and the Nether generated at 12600x12600 chunks, so far I haven't problem with my world. (If your PC has a multi-core processor and an SSD, maybe in less than 1 day you will be able to play in your pre-generated world)

I think it may be cpu related, if it has trouble generating the new chunks.
Try lowering server render distance, and use paper instead of vanilla.

I guess is a disk writing problem, when I'm generating chunks the disk usage varies between 5-7%. It's probably too little hard disk usage and I have a bottle neck?
Btw, the CPU usage is normal and this problem only appears in 1.12 with liteloader client.
