Bug description

com.earth2me.essentials.EssentialsPlayerListener$1DelayJoinTask (Single)

Is freezing game and causing memory leak.

Steps to reproduce

1. have multiple worlds with multiverse
   have essentials spawn
   have magic plugin
2. create a lobby world with multiverse and do /setspawn in lobby world

info

Lobby will lag and freeze because of listeners and world will not

Expected behaviour

To Not Lag

Actual behaviour

Freezing and having memory leak on clients and server

timings: https://timings.pl3x.net/?id=954a69186d28494a81cbd2cc70a01b2a

Nothing in your timings suggests Essentials is causing significant lag on your server.

then why when I use setspawn in a world it freezes randomly every 5 seconds

you didnt have to be so fast at closing the issue when I know its essentials causing it

shows how helpful you guys are for anyone else who comes with freezing and memory leak issues

you didnt even try to reproduce

thanks allot mr. I Wanna Speedrun Issues

now prove to me this isnt an essentials issue
since you clearly didnt look at a thing

and read the two things
Full Server Tick and com.earth2me.essentials.EssentialsPlayerListener$1DelayJoinTask (Single)

someone better reopen this issue or Im calling abuse of support terms

It's obvious that it isn't the cause of your lag because there were only two instances where it took 47ms in your entire timings report. This amounts to less than a tenth of a second of potential lag (and by far nothing you would be capable of noticing to begin with, much less a lag spike).

There is a video in the top right where you can learn to read timings, which I would recommend watching. Please don't report something like this unless you actually know what you're talking about.

You appear to have severely high tick durations from chunk loading. This is what you should be concerned about, not EssentialsX.

causing memory leak

This is highly unlikely and you've provided no evidence whatsoever for this. If you're sure you're encountering a memory leak, please provide us with proper evidence.

Full Server Tick

This statistic includes every single thing that happens in a server tick, including mob actions, players actions, redstone, physics, and plugin actions. The Full Server Tick metric only highlights that you may have performance issue, but it cannot be used to diagnose the cause of performance issues.

DelayJoinTask [...] count(2)

As you can see in your Timings report, DelayJoinTask does not run frequently - it ran twice in your screenshot. DelayJoinTask runs once when a player logs in to load their data from disk, and is very unlikely to have more than an occasional impact on your server. A high duration in DelayJoinTask means EssentialsX had to wait for your host machine to load the user's data and likely indicates that your host machine has slow IO performance. This is not an EssentialsX issue.
