Armor Speed
Slows you down depending on what armor you're wearing.
About this Mod
Changes players' movement speed depending on the armor they are wearing (and if they have a shield in their offhand).
It scales with the total armor points, and how many pieces of armor you have equipped.
Also, the mod doesn't care if you have a shield in your main hand. This is because I think the tradeoff of losing a hotbar slot and having to manually pull it out is balanced.
The Fabric version has a custom config thingy because either the documentation for both Cloth Config and YACL is either missing how to set it up in versions past 1.20.x, or I didn't look hard enough. You have to edit it manually in your game's config directory, but at least it refreshes without having to restart or reopen the world; Just do /reload.
If you set "mobs" to false in the config, already affected mobs will keep their speed until they die.
The Fabric and NeoForge versions might work on 1.21.9+, but I can't test it currently. You can test it yourself if you want; If it crashes on launch or when loading a world, it's broken.
Also, I removed the source link because I realized far too late that I forgot to actually commit changes to the repository and I don't want it to look like I linked a fake repo.

Armor Speed server crashes on startup – what to do?

Armor Speed officially supports fabric, forge, neoforge for Minecraft 1.21.8, 1.21.7, 1.21.6. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Armor Speed – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Armor Speed consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
