TPS of my Minecraft modded server is dipping hard. What to do?
Hi everyone, as the title suggests I have huge problems with my Minecraft modded server. I created a mod pack for me and my friends and installed every performance mod to boost server and client performance, but it seems like this didn't a lot for the server. As soon as we play with 4 - 6 ppl, the server starts crumbling and the TPS dips and it's getting almost unplayable. I already installed spark and let it run to determine the issue, but to be honest I really have no idea what to look for, as I'm fairly new when it comes to creating mod packs and such. Also im running the server with Pterodactyl https://pterodactyl.io/ and these JVM arguments: 
java -Xms1G -Xmx10G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -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=40 -XX:G1MaxNewSizePercent=50 -XX:G1HeapRegionSize=16M -XX:G1ReservePercent=15 -XX:InitiatingHeapOccupancyPercent=20

Here's the latest server log and the spark report: https://spark.lucko.me/4H3UVMR9oW https://mclo.gs/OvRB2m7 The mod list is in the server log. 🙂 Server Specs: Partitioned vServer (Ubuntu 20.04.6) AMD EPYC 7443P 24-Core Processor 2GHz (8 Cores assigned to my partition | 6 cores are assigned to the server) 26 GB RAM Can anyone tell me what do I have to do improve performance?
