All the mods 10 is one of the most popular modpacks out there. Being the most loved and most frustrating at the same time. With almost 500 mods inside it is one of the modpacks that constantly pushes people to upgrade their servers. And with all the automation, power systems, recipes comes even more pressure.
That is also why ATM10 often gets treated the same way across the market:
if performance drops, the default answer is usually simple - add more RAM.
That advice is convenient for the provider.
But not great for the player.
We wanted to test a different idea.
Instead of assuming ATM10 must start on a larger plan, we asked a more useful question:
how much of ATM10’s hardware pressure comes from the pack itself, and how much comes from avoidable server-side overhead?
Our main point is optimize the ATM10 modpack, keeping in mind everything that usually loads the server during the game session - Chunk loading, all the mobs AI and most importantly recipe lookup
The result was indeed clear by instead of treating 12 GB as the default “safe” starting point, we were able to make 8 GB a much more realistic starting point for many ATM10 playthroughs.
ATM10 takes its toll on the servers not only because it is a big modpack.
It starts allocate your CPU and RAM because of several heavy systems stacking at the same time.
First, ATM10 goes around automation-heavy progression. As players, building bases, farms, storages and autocrafters to keep progressing, the server has to keep more background logic running all the time.
Second, the pack becomes much harder to handle when exploration happens on top of all of that. Generating new chunks while automated systems continue running is one of the fastest ways to create lag, high CPU load, and unstable performance.
Third, large modpacks create extra overhead in places players do not always see directly. Recipe lookups, chunk saving, chunk processing, and background world activity can all add load that feels like - ATM10 just needs more RAM, even the real problem is unoptimized server-side behavior.
That's why players often come to the same conclusion:
if the server starts lagging or freezing, the answer must be to upgrade the server.
We wanted to test whether that assumption was always true.
Most of the modpacks add a lot of different mobs and each one of them has its own AI.
Managing path finding and all of the drops from these mobs take its toll from the CPU.
The other thing that goes through the CPU is calculating.
Most players of the ATM10 modpack are building a lot of automated farms (resources, energy, crafting, etc.)
And all of that falls onto your CPU and your server will start to lag with a few of those farms. And don’t forget about generating, while your farms are running and you have them under a chunk loader - going for an adventure would be a “killer” move for the CPU.
We didn’t want to just claim that our modpack feels faster.
We wanted to compare a regular ATM10 modpack from developers in compare with an optimized one under practical gameplay conditions.
Note
We tested them on our Premium servers powered by Ryzen 9 9950X3D hardware.
What we've been looking at: RAM usage, CPU load, TPS, MSPT.
We also tested more than one gameplay state, because ATM10 performance changes a lot depending on what players are actually doing.
Our baseline scenarios were, 2 player idle session, 2 player session with active chunk loading and exploration.
That second scenario mattered most, because heavy modpacks usually break down when active bases continue running while players generate new chunks at the same time.
The first clear difference showed up in raw server resource usage.
In the regular ATM10 setup, the panel shows 391.93% CPU usage and 10.89 GB RAM used. That already puts the pack close to the point where players start thinking about moving to a larger plan just to stay safe.
With the optimized setup, the panel shows 135.25% CPU usage and 6.32 GB RAM used. We can see a lot less CPU usage and also the RAM usage was cut for 40%.
The optimized modpack is not just “a little cleaner” - it materially reduces server-side load before we even get into Spark results.
During a lot of chunks being loaded at the same time we can see the real performance of the server
On a regular ATM10 modpack , the server drops to 11.40 TPS with 45.54 MSPT during active chunk loading. When the MSPT is >50 and TPS falls below 20 - players start to feel lag.
In the Godlike optimized modpack, the situation looks very different: 20.00 TPS and 7.34 MSPT in the screenshot. That is not a subtle improvement. It is the difference between a server struggling to keep up and a server staying stable under real gameplay conditions.
This is where the engineering work matters most.
Because chunk generation is one of the fastest ways to break the server in a heavy pack. If the base is running, automation is active, and players are still exploring, that is usually where ATM10 starts pushing people toward more expensive plans. Our goal was to reduce that pressure before it turned into a billing decision.
We also tested the optimized modpack in a calmer two-player idle scenario.
Here the optimized modpack stays at 20.00 TPS with 3.55 MSPT, which is exactly what you want to see.
Taken together, the Spark data tells a clear story:
a. the optimized modpack stays efficient in calm conditions
b. it remains stable even under heavy load.
c. it reduces the chance that players need to solve the problem by upgrading too early
That matches the wider test results we saw across the project: lower RAM usage, lower CPU load, and much stronger performance under real gameplay pressure.
As for players, the benefit is straightforward.
You are less likely to solve ATM10 problems the expensive way from day one.
Instead of jumping straight to a bigger plan just because the modpack has a reputation for being heavy, you get a setup that uses resources more efficiently and handles real gameplay smoothly.
That means:
In practical terms, this shifts ATM10 from - probably 12 GB to be safe toward - 8 GB can actually be a valid starting point.
That is a better outcome for players, especially for anyone who wants to start a server without paying for overhead they may not actually need.
The point of this offer is not just to discount a server.
It is to let players test a straightforward question for themselves:
Does ATM10 really need the bigger plan right away, or can a better-optimized 8 GB setup already do the job?
Our goal was not to just remove the “heavy” mods from a modpack therefore ruining the whole gameplay.
The goal was to reduce unnecessary server-side waste while keeping the core experience intact.
We focused on the systems that most often create hidden overhead in large modpacks: recipe lookup, chunk processing ,chunk persistence, and chunk delivery during movement and transitions.

This mod optimizes how the server looks up crafting recipes. When you are playing on a large modpack the server constantly checks if items on the grid match with all the recipes the modpack has either from your inventory or your storage. As ATM10 has a lot of different materials this mod makes the process much more efficient and faster unloading your CPU in the process.
This mod saves chunks continuously over time, reducing server lag and preventing lagspikes from saving too many chunks at once. Depending on some varying factors this can give you up to 10% more server side performance effectively, with no downsides. As the pack ads new biomes and stuctures, wouldn't you agree that exploring those smoothly would be much better?
This mod helps balancing lag(tps) and chunk view and simulation distance. During server lag view distance and simulation distance get reduced. You can config the settings to make the gameplay more comfortable for you without any issues:
Server side mod which controls and limits loaded chunks to only stay X time after player logout. You can filter out the chunks you want so the mod won’t affect the chunks you need to be loaded all the time.
Predicts player movement and pre-loads chunks in an area ahead of them asynchronously. Slightly increases chunk loading speed in general which makes exploration a lot smoother. Controls the vanilla chunkloading around the player by smartly adjusting the size to the player’s movement speed, reducing the server’s load. Search for a base location will be much more enjoyable with this mod.
Optimizes chunk packet sending through sorting and distributing them over time. More seamless server login/teleport/respawn/dimension change, as nearby chunks load first. Less network strain as chunks are spread out over time, decreasing lag spikes and improving playability for people with slow connections.
None of these changes alone is a miracle switch.
The real improvement came from combining them into a more efficient ATM10 server setup.
Wanna test - Minecraft performance mods, server-side optimization, gameplay improvements, useful tools for modded Minecraft and you have ideas that could genuinely improve the experience for players and servers, we want to hear from you.
We are open to discussing: grants, development funding, partnerships, launching useful tools for the wider Minecraft community

It's too many performance problems in modded Minecraft get treated like billing problems first.
Sometimes more RAM really is the answer. But if the default response is always “pay more,” then nobody is seriously asking where the problems are coming from.
We think hosting should get better through engineering, not upselling. The Godlike optimized ATM10 modpack is just a start and we want to continue: testing heavy packs, improving server performance, and finding practical ways to make modded Minecraft smoother, cheaper to start, and easier to enjoy.
ATM10 does not always need a bigger invoice.
Sometimes it needs better optimization.
