Show HN: Pumpkin – A Modern Minecraft server written in Rust

Impressive stuff, but I'll be more keen to see an high performance implementation that also supports the vast numbers of Minecraft mods. Forge servers are notoriously slow on bigger modpacks.

How would a server not written in Java support Java mods?

It'd have to be a hybrid, with more of the expensive parts rewritten in a more well suited language.

Yep.

Aren’t mods more or less the primary justification for building a server like this?

Although Rust may in some ways improve performance, is that a better trade for the huge reduction in potential mods?

Right, that’s my take as well. But on the whole I don’t see Java itself as being fundamentally less performant, particularly with JDK 21+. Architecture choices in either language make or break performance.
