[Xiaminou]

Whenever a players enters the Deep Dark the entire server starts lagging.

Looks similar to what I had in 1.10.2: #1030

[cragrim]

I can confirm that this is still an issue on 1.11.2 on extrautils2-1.11.2-1.5.1.jar
Forge-1.11.2-13.20.1.2391

TPS goes down to 8-12% when in the deep dark.
It does not appear to be related to other mods and only happens in the deep dark.
Everything goes back to normal when the deep dark is unloaded on a server.
Server doesn't seem to crash but javaw.exe cpu usage goes up to max until players leave.
Deleting DIM-11325 folder to reset the deep dark doesn't have any effect on TPS.
Because of the lag the portal can take 30-60 seconds to port you back to the overworld.

Screen and gif:

Nothing special/weird shows in the server log:

[02:07:10] [Server thread/INFO] [journeymap/]: Cragrim joining dimension -11325
[02:07:10] [Server thread/DEBUG] [cofhcore/]: Queuing RetroGen for features for the chunk at [-27, -30].

Thanks for reading this and keep up the good work smashing bugs!

How on the earth you managed to get down to the gold level? I just gave up after few minutes trying to leave the upper spawn. I ran out of patience.

[cragrim]

@hron84
I didn't get down to the gold level. I use cofh core (nowadays named cofh world) custom worldgen :D

I can confirm this in:
extrautils2-1.12-1.5.1.jar
forge-14.21.1.2443
Modpack: All The Mods 3 v2.7

TPS storms down to ~2
It's NOT the mobs, they are ticking correctly, and not causing any issues.
Also it doesn't matter that the chunks have been loaded the tps still dies. My first thought was maybe it's the world checking if the player is in the dark ?

[hron84]

@Xiaminou why did you closed this issue? Deep Dark does not lag anymore?

[Xiaminou]

I don't know about 1.11.2 but 1.12.2's Deep Dark doesn't lag anymore so I assume it's fixed.

[hron84]

@Xiaminou it does not neccessarily mean the bug is fixed. Many players go with 1.11.2 and I can't see if its support dropped.
