Your server took too long to tick, more than a minute by default; Either increase the watchdog timeout time in bukkit.yml, or don’t do large edits

I’m still very curious, why is it that only after transitioning to paper, my server has gone “1970 truck left to rust” mode? I’m 7tps all day.
24 Plugins: Ess, pEX, SuperVanish, Dynmap (removed because I thought it was the culprit), WorldBorder (not doing anything atm), WorldGuard and WorldEdit. I’ve got some minor plugins like WGLecternflags and EpicRename to spice it up. 24 is FEW, believe me =] ALL plugins up-to-date! Jar UP-TO-DATE! :smiley:

I start to think that Paper, clogging the console, is slowing itself down :rofl:
/mem tells me constantly that we got like 500mb free RAM. (That could be used, but seems that is not needed) We got 4 gigs afair.

Use timings, it’s designed for working out where TPS is being lost; In general, 1.14 is a pretty funky release for performance, no idea what software you came from, but I know that spigot will stop ticking entities at a certain point, and entities are one of the major trouble areas due to how much they access the chunk system which was a major performance hit in 1.14

https://timings.aikar.co/?id=9d432954f1074c7b83ecf0844c0732cb

Tho I have no idea how to mentally “parse” that.
Got to mention that this server had like 3 irl nights of WorldBorder chunk generating a week ago, while on spigot.

Running on a single core instance is pretty harsh for 1.14, features like async chunk loading might be better off disabled in such a setup due to the lack of overall resources, you’ll still get some paper specific gains with that disabled

Timings is mostly pointing to block ticking updates, but the low count suggests some level of CPU overload, I’d suggest following the optimization guide here: https://www.spigotmc.org/threads/guide-server-optimization⚡.283181/

Followed it just after switching to paper. I basically decided for maximum possible optimisation.
