Tuinity VS quilt-serverside-mods

Could also pregenerate your world with chunky. To make it quicker add Starlight, Lithium, tic-tacs(This might be incompatible with some worldgen mods, but it massively speeds up terrain gen speeds if it works), and Carpet(use the "/tick freeze" command to freeze the game so there's more resources for terrain gen). Then switch to a paper style Tuinity server and set the worldborder to keep people from moving past pregenerated chunks.

You can try out Tuninty for extra performance

Strip out all plugins, make backups of & reset your yml's. Does the bug still occur after doing that? Then report on their issues tracker: https://github.com/Spottedleaf/Tuinity/issues

Tuinity is a fork of Paper that includes optimizations that are generally tailored for servers with high player counts. It also includes Starlight: a complete rewrite of the lighting engine which greatly improves the speed of chunk generation. One benchmark has shown that Starlight can generate light 35x faster than vanilla.

Tuinity

For server jar I would recommend using Tuinity (or maybe even Purpur). As Tuinity has some more optimizations that help for larger servers and Purpur is a fork of it that I believe has even more experimental optimizations.

https://github.com/Spottedleaf/Tuinity/blob/master/patches/server/0061-Rewrite-the-light-engine.patch here is the patch, at the top he writes a description that can help you read more about it.

Use Tuinity (it's a fork of Paper, optimized for higher play counts)

not a jobs one, no. you can check out the serverside mod list here https://serverside.infra.link/

Have a look at this list. It's got a ton of useful server-side mods which you can use on your server.

To be honest, the natural path for those that come from Bukkit and derivates for the future is to either switch to datapacks, migrate altogether to Bedrock (that already have interesting advances on its addon/pack system) or switch to Fabric server-only mods - There is a lot of possibilities already and there is also Polymer project that aims to "convert" some classic mods to server-side-only, so at the end maybe OP should look at it all and forget the Sponge thing.

This seems like a decent shop mod, for a larger list of mods you can look here. Another shop mod I found was https://modrinth.com/mod/diamond-economy

Once you have your server OS installed, look through the performance section of Quilt Serverside Mods (even though it says Quilt all the mods are Fabric compatible). Also make sure to set sync-chunk-writes to false in your server.properties.

I have been using this list to find some optimization mods but some mods in the performance sections seems to break the game (eg - Very Many Players ).

Here’s a good resource for server-side mods, some of them are for quilt but quite a few are fabric mods (originally the list was only fabric mods, also quilt is a fork of fabric, so if you wanted to give it a go, it has most of the same benefits fabric does)
