Lag due to Folia Scheduler on papermc server

[DarkChromaMC]

Issue: Unnecessary lag caused by multi-threaded scheduling on Folia
Description:
When running on a Folia server, GeyserModelEngine schedules tasks across ALL available CPU threads, which causes significant and unnecessary lag. This behavior is resource-intensive and does not provide any benefit in this context.

Expected Behavior:
The plugin should detect when it's running on Folia and limit its use of threads accordingly

Additional Note:
If the server is running on PaperMC (not Folia), the plugin should fall back to a simpler, more efficient scheduling method. The current scheduling logic is overly expensive for no reason and should be avoided on Paper-based servers

Suggested Fix:
Add conditional logic to detect the server type (Folia vs Paper) and adjust the scheduling strategy accordingly to reduce CPU overhead

As far as I'm aware ModelEngine itself doesn't support Folia nor any of the mythic plugins do and this plugin also hasn't afaik been tested with Folia nor been looked at, so it's kinda a use at your own risk, I can look into it more for the schedule side though

I just noticed ur on paper ;-; my bad but yeah can look into it more (from the look of the issue it sounded like u were on Folia XD)

Heya could you try this build https://github.com/xSquishyLiam/mc-GeyserModelEngine-plugin/releases/tag/1.0.2 and let me know if it's better

Hey, I just tried the plugin now and it works. It shows async folia using 4 cpu threads instead of 32 before. But, there is a weird bug where if you relog from the server, the custom mob reverts to a pig/vanilla version. I've provided a video below to demonstrate:

I noticed these errors in console if it's related: https://mclo.gs/8uD8YOJ

Heya, added a temp fix (not a big fan of it defo an interesting issue though), the link for the test build

Unfortunately custom mobs revert to vanilla mob upon relogging with the new test build

I think when the chunk reloads it fixes the glitch?

Did just upload a new test build on the link above mainly me fixing a scheduler bc i did it back to front, if it still happens try upping join-send-delay to 30, on my end it sorted it afaik
