30% of the time a player enters the Nether on our vanilla server the game lags for 20-30 seconds. A few times it has lagged to the point of causing a crash.

Here are two of the files you requested. One from the server side and other other from my user. The server did not fully in these profiles but did shortly before I got them. Using version 1.18.1 now and still get bad lag from the nether, not from the overworld or the end.

I've changed the view distance around a few times, it is currently at 10 but could have been at 9 during those logs. Simulation distance is set to 6.
The RAM allocation was increased as high as it is to try to get the issues to go away. Reducing the RAM down the 4gb causes general lag around the server due to low resources.
@unknown The profiling log was very helpful, thanks for attaching it. There definitely seems to be something weird going on in the Nether chunk loading.
Would you mind attaching the world and optionally a report from JFR as well? You can trigger one using the `/jfr start` command.
We do not have enough information to find the cause of this issue.
While the lag occurs, please press
F3+Lonce, then wait a short moment until profiling has finished.Afterwards, please attach the generated
.zipfile containing the profiling results here. The file path is shown in chat; the file can be found in[minecraft/debug/profiling/<DATE>.zip|https://minecrafthopper.net/help/finding-minecraft-data-folder/].If you are playing on a server please additionally run the command
/perf startto create a profiling report for the server. In case you do not have the permission to run this command, make sure that you're a server operator.Once profiling has finished, please attach the generated
.zipfile fromdebug/profiling/<DATE>.zipof the server folder.This issue is being temporarily closed as Awaiting Response. Once the requested information has been delivered, the report will be reopened automatically.
