At default settings, how big will DH files be?
Obviously this depends on how much I've generated, but I'm trying to figure out the order of magnitude of the file sizes. Will I be looking at megabytes or potentially many gigabytes? Let's say within the range of 128 to 4096 chunk render distance radius. I'm currently generating, but as there is no progress bar I have no idea if I'm 10% of the way or 90% of the way there, so I don't know what final size to expect (roughly speaking).

Does Quality Preset determine the quality at which the LOD is generated or merely shown?
In other words, if I'm sitting here waiting for the LOD to generate distant chunks, does it matter what quality preset I have it set to? If I set it to minimal to decrease the lag while generating, can I simply swap it to extreme after everything's generated or will I have to regenerate for the "extreme version" of the LOD?

can’t connect to self hosted server
I’ve set up a server and checked that on the host device I’m able to connect using “localhost”
I’m trying to connect to the server from another pc on the same network, and the ipv4 address of the host isn’t allowing me to connect. doesn’t say pinging or anything, just doesn’t work
what could be possible solutions?

After "EXCEPTION_ACCESS_VIOLATION (0xc0000005)" set shaders enabled to false and still crashing
Hi, I had the AMD GPU issue where the game would crash if I joined a world with shaders enabled (my GPU is the RX 6600). I tried disabling shaders, and it would let me join but eventually I would still crash. I tried using the OpenGL 2.0 mod, but regardless of whether I had shaders on or off I would still crash.

Can someone help me glean useful information out of my Spark profiler output?
I know enough to run it, but I don't have enough knowledge to actually understand what it's telling me.
I'm particularly concerned about mods that might be negatively affecting performance.

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?

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.

Minecraft Client experiencing extreme lag on server
Is it normal for a client’s RAM usage to max out the moment they start Minecraft, even on the initial splash screen before they’ve even entered a world?
I’ve got a Fabric server and a user is getting ~20 FPS when before they averaged ~100ish. They didn’t check their usage prior to noticing the issue so can’t confirm what it was like before. The server is largely the same, the main changes are that mods were updated to the newest versions (not a MC version change, just the mod versions) and a couple new mods were added. I’m having them remove mods one at a time to troubleshoot but have yet to hear back.
I personally booted up completely vanilla MC and allocated the same amount of RAM but it only used around ~3GB during startup and on the splash screen, maybe even less. But the moment I load up the Fabric version with the mods installed, startup takes all 8GB and stays that high even on the splash screen.
