FTB Revelation Server performance

[Sylay13]

Hello everyone,

Unfortunately I have some problems with my FTB Revelation Server. In the console, every 30 seconds, "Can't keep up! Did the system time change, or is the server overloaded? Running 9179ms behind, skipping 183 tick(s)".

I've tried several arguments to improve performance, but to no avail. Do you have any advice what I can do?
Unfortunately, I don't have that much experience in the server world of Minecraft and I took the arguments from various sources

Arguments:
-javaagent:log4jfix/Log4jPatcher-1.0.0.jar
-XX:+UseG1GC -XX:+UnlockExperimentalVMOptions
-Xmx25000M -Xms4096M
-XX:+AlwaysPreTouch
-XX:+DisableExplicitGC
-XX:+ParallelRefProcEnabled
-XX:+PerfDisableSharedMem
-XX:+UseCompressedOops
-XX:-UsePerfData
-XX:MaxGCPauseMillis=200
-XXarallelGCThreads=8
-XX:ConcGCThreads=2
-XX:+UseG1GC
-XX:InitiatingHeapOccupancyPercent=50
-XX:G1HeapRegionSize=1
-XX:G1HeapWastePercent=5
-XX:G1MixedGCCountTarget=8
-XX:+AggressiveOpts -jar forge-1.12.2-14.23.5.2846-universal.jar nogui

Hardware:
I3 10100
32gb ram 3200Mhz.
256GB NVME SSD
OS Windows Server 2019 standard

How old is the world on the server? How much chunk loading are you doing? The longer you play a world the bigger and laggier it will get. You might just have hit the cap that the CPU can keep up with, more ram doesn't always mean better. you might also want to consider switching your OS to Linux if all you do with this pc is hosting. There are a few other things I can think of as the number of entities / Tile entities in the world can also cause issues later in gameplay. The best mod to check on this is Crash Utilities but I think it's only 1.16.5 + so kinda doesn't apply here but you could also use `/cofh` and there are some helpful things it can do with items/mobs.

Hope this helps a bit, good luck!

The world is only a few days old. And I can't explain why the CPU load is so low as in the picture
