What kinds of (Fabric) mods negatively affect performance the most?
My server is struggling and I want to remove the main offenders. I plan to use Spark to help me identify, but just in general what sorts of mods would hurt performance most?
If I had no knowledge I would guess that large world generation mods like Terralith or those that add lots of big structures would negatively affect performance, but I do know that if you pregenerate your world (which I have done), they actually don't negatively affect your performance that much afterwards. So what are the real culprits?...
TRying to test fabric proxy lite, I can't get it to work succesfully
I have a velocity server and two fabric test servers with mods. I configured it like docs state. backend is online mode. OWO lib gave errors but it seems there is a olugin that gives compats for owo lib handshakes. Now when I try to connect to a server, my logs say I just keep bouncing from a server to another.. what could be going wrong?
Port forwarding not working
I followed tutorials, did the windows firewall thing, port forwarded etc, and yet it doesn't work, my friend can't find my server if he puts in the IP I get when I look for it on a browser, so no matter what, he can't even find it, but local host works for me of course
is render-distance in server.properties resource intensive even if chunks are pregenerated
is render-distance in server.properties resource intensive even if chunks are pregenerated, my survival server i use 8 but i want to do it 12. i generated chunks already
Survival server tips
I am into the making of a Survival server and i am looking for some tips and recommendations. I want the server to be unique and not be the next copy of a survival server. I have considered and added custom armor sets and custom enchants. I was wondering if adding custom terrain would result in worse server performance and what other things i could add to make the server more unique?
Any good alternatives to DeluxeHub?
DeluxeHub seems to be abandoned. GitHub issues are completely rotted and unanswered. Anyone have any good alternatives that are actively being maintained?
Server Version Help
this probably sounds like a pretty dumb question to be asking if i'm honest, but my server is on 1.20.1 and i want people on versions higher than 1.20.1 (like 1.21) to be able to join, and still be able to enjoy the same gameplay, would this be through viaversions' viaforwards? or am i just being plain and simply dumb, (also i have 2 servers connected on a velocity proxy) (idk if tha thelps)
I'm using Aikar's Flags for my server but I was wondering if I could replace G1GC with Shenandoah?
I'm not super knowledgeable on the subject, but from what I can gather, Shenandoah is a superior garbage collector. I don't remember where I got it from, but the arguments I have for my client arguments uses Shenandoah, so now I'm wondering if I can use it for the server as well.
The following are the arguments given by Aikar's Flags. What would I need to remove and add to get rid of G1GC and add Shenandoah?
java -Xms8192M -Xmx8192M --add-modules=jdk.incubator.vector -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -jar server.jar --nogui...
Is -server argument still used?
I'm reading a reddit post about server lag optimizations and one of the things that it says is start your arguments with -server as that makes sure that the server is using the server virtual machine which helps performance. This guide is 6 years old though, and Aikar's Flags doesn't include -server so I was wondering if this is outdated now.
Does anyone know how to read Crash Logs?
I have around 180 mods. The server just shuts down. I need to pin point what it is but I can't understand the Crash logs. Most of the mods are small little things so I doubt its the little mods. Can someone DM me or where can I show the crash log??
Trying to run 2 servers off the same computer
I’m trying to run 2 servers off the same computer, but I can only get one of the servers to let me connect to it. I have been changing the ports in the server properties from 25565 on the second server, but it refuses to let me connect with the ip. I port forwarded it the same way as I did with the first server, but with the new port I would assign to it. (I know localhost would let me connect, but I want to be able to play on it remotely and with friends as well)
Having trouble tracking down what is causing log spam after 1.21 Update
It seems like I'm getting errors thrown almost every tick, from 10+ plugins, which leads me to believe that it's not the plugins themself, but rather something else. This snipper it showing a lot of EMF, but there are a lot of illegal java exceptions on their own, and worldguard events, depending on what region I'm in, what I'm interacting with, and how I'm moving.
Chunk loading far from spawn + /worldborder
So on my 1.21 spigot SMP, I found out a player was traveling in a straight line away from spawn. They were at 33,000 blocks (they're doing it for the Adventuring Time advancement but I said it was a bad way of doing that advancement), and I didn't want them loading more chunks far out so I set the world border to a 35,000 radius. I didn't want excessive chunk loading because people already complained about lag on the server. Now I have someone complaining that reducing the world border also caused more lag.
So this left me with a couple questions:
1) Is there a correlation between distance traveled from spawn and memory/RAM usage? Or is it just number of chunks loaded and doesn't matter how far out you are from spawn?...
how to add a player LuckPermsVelocity permission through a servers console
is this possible that a subserver can add a luckpermsvelocity permission through console to a player?

Does anybody know where I can find a server owner?
So this will come off as a really stupid question, and that's because it is a really stupid question. I have an idea for a server but do not have the financial or legal responsibility to own it because I'm 15. I feel like there is some person out there does and would be willing to try this idea out as I already have a huge foundation built up from the time I tried this idea myself and failed, I just want to know if theres a place where I can find them.
If I install viaversion in velocity do I need to install it in the servers also?
