Getting 10 people onto a vanilla survival server is a great experience. But the real fun starts when you have around 500 mods loaded in All The Mods 10 (ATM10).
The problem? An underpowered server collapses under the weight of ATM10, Better MC, or Vault Hunters. Hosting a heavy Java process in North America comes down to three things.
Let's dissect why your Modpack server lags and how fixing it is actually inexpensive.
1. The RAM Deception: Why 8GB is Not Enough
Your North American server probably launched its modpack server, ran around in the forest for 10 minutes at 20 TPS, and the server owner said "8GB is plenty."
Wrong.
Once 5 distinct players start pushing into the mid-game and loading separate dimensions:
- Overworld generation
- The Nether
- Twilight Forest / The End
- 10+ chunk loaders keeping huge factory setups active.
Your 8GB server is going to constantly initiate "Garbage Collection" pauses to clear unused memory. These pauses freeze the server causing massive rubberbanding.
The Solution: For a North American crew of 5-15 players, plan for 16GB of RAM with MC Special 3. A group of 1-5 players can start on 12GB with MC Special 1, and 15+ players should go for 32GB with MC Special 4. The official ATM10 server files set an 8GB Java heap (-Xmx8G), and Java needs memory on top of that, so raise -Xmx in user_jvm_args.txt to fit your plan.
2. CPU Power over Core Count
Minecraft, specifically Java Edition, handles almost all core dimension updates sequentially. That means having 30 CPU cores running at low speeds is useless.
What you need: The absolute fastest single-core performance on a modern CPU.
Our North American locations run on AMD Ryzen 9 chips. USA California and USA Virginia use the Ryzen 9 7950X3D with DDR5 RAM. In Canada you can pick Premium on a Ryzen 9 7950X or 9950X (depending on stock) with DDR5, or Standard on a Ryzen 9 3900X-class CPU with DDR4. The strong IPC (Instructions Per Clock) of the 7950X3D, 7950X and 9950X absolutely shreds through dense ticking entities like massive item-sorting networks and enormous mob farms in modpacks.
3. Loading 10,000 Textures requires NVMe
When a player hits an ungenerated chunk boundary, the server calculates what biomes exist, what ores generate, and hundreds of custom modded structures instantly.
NVMe SSDs read data far faster than older HDDs and SATA SSDs, which cuts the delay your CPU would face waiting on storage. Every Space-Node plan runs on NVMe storage, in the USA and in Canada.
Setting Up Your North American Modpack Server
Getting your heavy ATM10 community up and running natively for American players is now straightforward.
- Pick the Closest Region: Choose USA California, USA Virginia or Canada, whichever sits closest to most of your players. The plan selector measures your ping to each region and suggests the fastest one.
- Pick the Right Plan Size: Grab MC Special 1 (12GB) for 1-5 players, MC Special 3 (16GB) for 5-15 players or MC Special 4 (32GB) for 15+ players. All three are on our ATM10 server hosting page.
- Set Java 21: ATM10 needs Java 21, and the official start script stops on anything older. You choose the Java version yourself in the panel.
- Install the Pack: For ATM10, the official guide tells hosts to set up a fresh NeoForge server on the NeoForge version the pack uses, then upload the server files over SFTP. For other packs, the panel's one-click CurseForge and Modrinth installer can save you the upload.
With the right strategy, your US-based gaming community doesn't have to suffer through TPS lag spikes. By moving to a Ryzen-powered node in the USA or Canada with enough RAM for your player count, you cut down on chunk lag and block-break lag and leave room for your heavy modded gameplay to grow.
