C2ME causing player teleporting lag on server

[LostChairr]

Whenever players load in chunks it teleports the player back over and over again and the server TPS is perfectly fine after a while it crashes the whole server (server logs say nothing just shut down)

VMP does not affect teleportation (only chunk loading).
C2ME can if you enable an option (off by default) in the latest dev build.
I wonder if you have other mods installed.

There is a work-in-progress optimization targetting situations like this in development builds. Please try reproduce this with development builds.

Is the fix in any of the 1.18.1 builds? My server won't run any of the 1.18.2 releases.

[toinouH]

Must probably not as:
Ishland's time is very limited (only a few hours per week to maintain 3 mods, the latest release and often a snapshot version). Maintaining a backported branch is in consequence rarely an option for us.
When the fix is fully done you will be aware of this and you can backport it if you want.

It happens more often when I move quicker and mobs lag and teleport too

I converted the recent 1.18.2 C2ME version to 1.18.1 and it's not as bad but it's still quite annoying video I sent is what's happening

Here's a spark profile while the mod was teleporting me back

From the spark profile it seems that the server ticking logic just simply can't keep up with the speed of chunk loading. This isn't what we can fix in C2ME. If you really want this to stop this from happening use fabric-carpet with antiCheatDisabled rule.

[LostChairr]

Anticheatdisabled fixed the rubber banding but is there any solution to the lag? The server is only laggy when C2ME is installed. I really want to use C2ME in my server it drops the server's CPU usage down drastically.

Can you join our discord server so we can further investigate this?

Closing as this issue is caused by ferritecore.
