need help with fabric server performance on an smp kinda urgently

^ Suggestion 1 + spark report please

What modpack? How many people? What hardware/plan from what host? What sort of performance issues? Any errors? Spark Report please?

I don't have spark right now should I put it on and get a report first or can I describe whats happening first

im using these: its 1.21.5, i havent edited any default config

ram is 10 gigs cpu is core i9-9th gen I think? ram isnt the issue, cpu seems to go up a lot though

its 20 people on since its launch day

server crashed twice now its just lagging lightly since 5 people logged off

i can send a crash report

whats causing a headache

More information is certainly helpful

Also, can you send the full log from that crash report (log not crash report)

3 players and 3k entities are being loaded. Send over your server.properties file.

gotchu

is this right?

i also have other logs from that same time period

heres one from exactly the same time (22mins ago) when it crashed

Can you remove c2me and see if it helps

but spark is highly suggested to get

okay I will, that wont cause any long-term damage right? considering first run and pre-loading was with it in

also ill add spark

No.

anything else I should change before I restart?

adding the servercore mod

pebblehost?

yeah
