Performance problem on latest version?

Here is the link to the spark report. The profile was taken with 113 online players using v3.4.1d.

This might appear to be trivial to most servers, but:

I don't recall seeing this on previous versions of the plugin
I have disabled all parts of ItemsAdder except furniture. Link to config.
At these player counts, every performance improvement helps

For these reasons, I thought it was worth bringing this to your attention. Apologies if this isn't the correct place, but the GitHub bugs tracker didn't feel like the right place either.

0.81% is not a lot. Are you sure there is any TPS drop?

Anyway I doubt it's possible to optimize that, this is the most optimized code you can ever do. It's related to checking if there is any custom block in a chunk and I'm using the Minecraft internal code to do that, to achieve the highest performance possible.

What you can do is disabling these options in config.yml of itemsadder:
blocks.convert-vanilla-blocks.enabled: false
blocks.fix-glitched-blocks.enabled: false

I'd avoid doing that if you don't want to see glitched mushrooms/chorus plants spawning around the world.
If your world doesn't include any mushroom/chorus plant you're good to go.
