Hi, i have vanilla minecraft server also,

When I tried to the world, I noticed that it was recording very late and the game froze.

I've experienced paperspigot and spigot servers there, and I've had the same result. Saving the world too late. do you update on this?

which computer have you tried on? the answer:

16gb ram and processor is i79800X disc Nwme samsung 960pro

 Paperspigot timings here(just check this world save problem):
