Minecraft-Performance-Flags-Benchmarks VS hilltty-flags

If that doesn't work, try using Java arguments: https://github.com/brucethemoose/Minecraft-Performance-Flags-Benchmarks and/or increase the amount of allocated ram to 10GB.

You can try Java tweaks - https://github.com/brucethemoose/Minecraft-Performance-Flags-Benchmarks or performance mods - https://github.com/TheUsefulLists/UsefulMods

If you insist, though, there's this page that talks more about JVM arguments.

Take a look at https://github.com/brucethemoose/Minecraft-Performance-Flags-Benchmarks

I can't attest to how valid these benchmarks are, but this explores the topic - https://github.com/brucethemoose/Minecraft-Performance-Flags...

Like others said, don't allocate all the ram the server has to the jvm with the -xmx, but since you were asking for flags, I've been using Hilltty flags, and they work like wonders. Here's the link https://github.com/hilltty/hilltty-flags/blob/main/english-lang.md

My opinion, Aikar's flags are still the safe bet. Feel free to experiment though: https://github.com/hilltty/hilltty-flags/blob/main/english-lang.md

Also use hilltty-flags with Temurin JDK 17 (or any other JDK that supports Shenandoah Garbage Collector) for better performance.

Also for better performance on all cores use hilltty-flags with Temurin JDK 17 (that supports Shenandoah Garbage Collector)

Well, if you can't find another datapack and don't want to go the way of creating custom arrows, you can try to optimize your server as much as possible. Instead of PaperMC, use Pufferfish, install Temurin JDK 17 and run your server with startup flags from hilltty, based on the Shenandoah garbage collector. Also, following this guide, optimize the values in the configuration files (like paper.yml).
