Question 1

How much RAM does a Minecraft Forge modpack server need?

Accepted Answer

Forge modpack RAM requirements vary enormously by pack complexity - lightweight packs like a small tech or adventure modpack run comfortably on 4–6 GB, while comprehensive kitchen-sink packs such as All the Mods 9 or FTB Revelation with 200+ mods typically require 10–16 GB for a stable multiplayer server with 10–20 players. The JVM heap allocation is the primary driver, as every mod's classes, world data caches, and loaded chunk data compete for heap space - insufficient allocation causes frequent garbage collection pauses that manifest as server lag spikes rather than consistent tick rate loss. Our DDR5 RAM ensures allocated heap memory operates at full bandwidth, reducing GC pause durations, while NVMe Gen4 storage accelerates the initial world chunk loading that happens when players first join after a server start.

Question 2

Does UK hosting help with Forge modpack server lag for British players?

Accepted Answer

Forge modpacks with large tech trees, automation networks, and chunk-loaded factories are already demanding on server tick rates - at high latency, the gap between server tick and client display compounds the perceived lag, making machines appear to run slower and item transport stutter even when the server TPS is acceptable. UK players connecting to EU or US Forge servers typically add 40–80ms of round-trip latency that makes pipe and conduit item movement, machine GUI interactions, and chunk loading feel sluggish. Glitch Servers routes through AS212868 with direct LINX and LONAP peering, keeping British Forge players under 10ms round-trip for responsive automation feedback. Consistent low latency makes the difference between a modpack server that feels smooth and one where every interaction has an irritating delay.

Question 3

How do I update a Forge modpack without losing my world save?

Accepted Answer

The safest update procedure is to back up the world directory via SFTP before making any changes - the world folder contains all chunk data and player inventories and is entirely separate from the mods directory. Once backed up, stop the server, replace the contents of the mods directory with the updated mod files, update the Forge server JAR if the pack version requires it, and restart. Most modpack updates preserve world compatibility, though removing mods that added blocks can leave broken tile entities in existing chunks - the backup ensures you can roll back if incompatibilities appear. Our NVMe Gen4 storage makes SFTP world backups complete quickly even for large saves, and the full SSH access means you control the entire update process without panel restrictions.
