Description

My English is really bad so I used google translator.

LuckPerms in combination with EssentialsX increases ping when changing the gamemode or when switching to another world. The more plugins are enabled, the ping jumps higher (With ~40 plugins ping jumps to 800 and more) and it is quite bothersome because it causes temporary lag for a player.

Likely just server lag, what is your server specs and also do send your startup log.

Try using a profiler like spark (https://spark.lucko.me/) to debug further.

You need to create a profile while the gamemode switch happens.
