Use spark and provide us a spark report.
It would be better for us to investigate the lag.

Yes, the issue is that when the island is being deleted, the code tells ItemsAdder that the block is being removed, for each block. We had the same problem with SlimeFun, but I was able to fix it because their API has a way to check for blocks. I think I'll temporarily remove the hook so that there isn't lag at the expense of not deleting IA blocks.

The other option is to drastically reduce the number of blocks deleted in one go in the BentoBox config.yml.

Anyway, I'll try and see if this can be optimized.

You can use the snapshot 2.0.1 version.

Thanks!
Does this also apply to IA furnitures too (especially those using armor stands) or just custom blocks?

Mostly just custom blocks

I just tested dev build with disabled IA blocks removal, but for some reason it still lags but less than before.
I don't remember this was a problem in 1.24.1. Maybe it's something wrong w 1.20.2 mc version? I was on 1.20.1 before.

Try the very latest build on the CI server. I added NMS support for older versions - before, it would only optimize for 1.20.4, so if you were using 1.20.2, then it would be using the Bukkit API to copy and paste blocks.

I asked the dev for some API addition to prevent the lag, but let's see. PluginBugs/Issues-ItemsAdder#3445

Great! Anyway don't know what's going on, I just updated Bentobox to the latest build and addons too, but there's lag when I invite a player. Looks like I have to stick with no island removal for now.

Having same issue with purging unowned islands, because I just disabled automatic island removal. It's not really that massive, but probably same lag spike. So currently I have no way how to avoid this lag. Any idea @tastybento ? I've got lag when I purged just 4 islands.

I need logs or stats to see where the lag is coming from when you do this. It may be some other location. Can you post a Spark report?

Here it is, I think it's very similar when I am purging islands.

Hmm forgive me but that seems all okay - 20 tps across the board. Although BentoBox does use CPU, the TPS are not affected (at least according to that report). It looks like the staggering system is working. What do you actually experience in game?

Trust me, it affects TPS too and it's really not a small lag spike, there is no chance not to notice, because you can't even open chests, drop items etc.


Just check plugins section in that spark, 98% is crazy, never had more than 20 and it's even measured using a parameter --only-ticks-over 200 which is even more crazy.

Okay thanks. Let's see what we can tweak.

Same problem with 1.20.4, but looks like for example obadmin purge unowned doesn't lag like that, it only takes not even 1 tps. Problem is reset itself.
