Relay - Network Manager

**_A network manager mod for smoother Minecraft connections._** **Side:** both (client and server), but the mod impacts on server more **Mod loader:** Fabric **Connector support:** I don't know; some things don't work exactly as expected. **Tested Minecraft versions:** 26.1–26.1.1, 1.21.8–1.21.11, 1.21–1.21.2 **Legacy versions:** 1.20–1.20.1 (no longer recommended or supported) --- **! Read source code instead, for guide !** **Is abandoned project** --- ## Test results on 1.21.1 Dedicated Server, Client mod included ### Test 1 - **Specs:** Java 21, 1 GB RAM, Tor proxy, playit.gg, 6 piston lag machines, v0.1.1 - **Vanilla:** pretty classic lag, chunks load faster - **With mod:** more load compared to vanilla, fewer lagbacks, `/tp` feels a bit faster, mob behavior is a little more stable, but if things get very laggy it can also make some vanilla bugs easier to do. ### Test 2 - **Specs:** Java 25, 4 GB RAM, Tor proxy, playit.gg, 6 piston lag machines, v0.1.1 - **Vanilla:** pretty classic lag, a bit less load, faster chunks - **With mod:** fewer lagbacks, mob behavior feels a little more stable --- ## On servers that do **not** have this mod installed (for example, Hypixel SkyBlock) - **Specs:** Java 21, Tor proxy, v0.1.1 - **Vanilla:** less load - **With mod:** basically no big change, but block breaking / final break registration / item dropping felt just a tiny bit faster (~150–200 ms) Client had **8 GB RAM allocated**. --- ## Honest result From testing, the improvement is usually pretty small — somewhere like **3–10%**, and mostly only if: - you are **really laggy** (because you live far from where servers were hosted or whatever) - you **hate lagbacks** - server is hosted on a **good enough machine** If you don’t really have those issues/things, then the difference is usually **VERY SMALL**, and this mod probably isn’t worth using. But if your friend is from far country and you're hosting server and both have stable internet, it might help quite a bit. Also, this mod does **not** magically save you from every disconnect. It changes **packet behavior / traffic flow**, not the laws of physics. A lot of the code after `0.0.2.5` was AI-assisted (around 80% of code, or should i say vibe-coded to be correct) ... I just realised that gaming is not that fun sometimes, and i don't want to maintain much, so i decided to release full source code, on 01.07.2026 done :)
