I hosted a modded server on google cloud vm (6vCPU 24GB RAM 180GB SSD)
allocated 16GB RAM to mc server
My server mostly stays at 20TPS but every like 2 minutes it jumps few times to 12-17TPS while not doing anything and its a fresh empty world with nothing working in it to do any lag
Then when i do some basic redstone and spawn 400chickens in one area to do a small stress test, it just dives down to 9-12TPS
in the console it gives many "Server seem to be overloading jumping 40ticks" and every so often a "Can't keep up running 40-116 ticks behind" like every 20 seconds
My modlist is in the list.txt
Any help would be apprieciated

Google cloud hardware generally sucks hard for mc
Especially modded

isnt it just a bare VM?

Minecraft is singlecored
It has some functions that can use more but
But it has a single main thread

could anybody please help me analyse this?
ai is not doing well with helping as it does not have good direct access to this
i cant export all of the data from it
the cpu is quite a limiting part in that spark profiler
lower the view and sim distances to 7 or lower

i changed the gpu
from amd epyc to intel xeon
it still is bad
i dont really know why
the tree of things using up the thread dont really tell me much
i dont want to waste the google free tier and change host so im willing to do anything to fix this
aslo there are weird ping issues
all of players ping jump to 300ms even tho we should have 40ms avg
this was with doing some redstone stress testing to simulate heavy use
and it did not go well
