My server timings : https://timings.aikar.co/?id=ae8f532214ab4e38b13998bac19a8a2a
At first glance, it looks like something from the iron backpacks is taking up most of the tick time…
What are you using iron backpacks for? I would recommend trying to make a copy of the world, and loading it up without the mod, and seeing if that fixes the TPS issue.
The server is also ticking seventeen million tile entities. That would probably have something to do with it.
I put the tileentity-activation=true of the sponge conf as if it is normal.
But this message is more straight ahead,
Server thread/WARN Can’t keep up! Did the system time change, or is the server overloaded? Running 46553ms behind, skipping 931 tick(s)
I understand, I have planned to remove the iron backpack. Thx
I have removed the iron backpack module, but tps is still low
