hi i have a problem with my mc modded fabric 1.21.1 server, its nearly always delayed at 50 or above and i cant tell why even from spark i use

java -Xms18G -Xmx18G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=50 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=16M -XX:G1ReservePercent=20 -XX:InitiatingHeapOccupancyPercent=15 -XX:+AlwaysPreTouch -jar fabric-server-mc.1.21.1-loader.0.16.13-launcher.1.0.3.jar nogui


and this is the curseforge code to see all the mods im using:6_7hG0AP

Did you installed any datapacks ?
I've seen the spark report, it looked like the graph for vanilla command function takes a great chunk of that delay you've said

And looking abit under Mods tab, It seems to be that the Aether mod is also taking quite a bit of the server's tick, too
for the aether thing I heard that spark actually blames the lag on it
im not sure if they're right
i didn't think datapacks would do much
Firstly, before troubleshooting this, you should backup your server lol

Next up, yeah can I take a brief look at some of those datapacks, some of the mspt-destroyer one like VanillaRefresh and DynamicLights are a big concern
And try to temporarily remove the aether mod(rename the file to .jardisable), I don't really sure but its better than nothing

hmm sadly a friend of mine is utilizing the aether mod for his builds and armor. I'm not sure if I can remove it

Hmm, then we will reach that mod later, right now can you please send the names of those datapacks ?

Datapacks typically has almost no optimizations for normal servers, so theres that
@Spectacled bear Click to see attachment
Do you need all of those VanillaTweak datapacks ?
Like some of them like redstone rotation wrench are not commonly used among servers I've seen

yeah some of these are kinda outdated, put them in during the beginnin g of the server thinking itd be useful
Yeah make sure to remove them if you dont need it regularly
