[Bug] Loading some chunks lags the client about yatopia HOT 19 CLOSED

Is this behavior happening after upgrading your world from 1.16.1 ?
Also if you're generating chunks chunk generation looks slow for the client. And try updating to latest yatopia as we updated paper as paper did some changes with chunks.

EDIT: I also have some lag spikes and fps drop with client, but the vanilla client is very unoptimized and we need optifine for life.

After upgrading and join, this happens immediately when it is joining world.
This is a generated flat world area in Multiverse.

honestly try bumping upstream with this, we don't do any changes around chunk loading.

Alright and I will try to reproduce it on Tuinity and Paper

Currently reproducing on pure Yatopia

I don't know if it could help but change the default value (2 or 4 I don't remeber) for an higher one if you can (for the client)

I dont have that much ram and it is not pulling a lot of ram but a generic lag

from yatopia.

I dont have that much ram

which means you probably have some old cpu which can't handle newer versions.
just wait for optifine. this issue is not an issue from us or upstream

from yatopia.

It is not lagging in other servers.
I allocated 3G of ram for Minecraft and running smoothly 70fps in other servers

if updating yatopia doesn't change it then it is something with your terrain. again, out of scope, nothing we can do about.

This is completely not happening on vanilla

This is NOT happening on Tuinity. Please repoen
Running for about 10000 blocks away with no noticable lag.

(I think he will). You see all different upstream, can you do some test to tell us wich upstream is the problem ?
The check means that the bug doesn't exist in the upstream.

try reproducing with latest yatopia. if you can, im going to try it on my 1.16.1 generated world.
if I can reproduce it too, im going to reopen the issue. otherwise there are signs that this isn't exactly yatopia's issue.

from yatopia.

I tried it anyway, and I can't reproduce it.

It is still lagging after upgrading

Possible solutions:

1. Supress sending -1 biome ids and replace with 0
2. Replace biome ids with 0 in chunks
3. Regenerate biome ids

How about we implement this fix directly in yatopia?
