Okay so as mentioned there really isn't any specific part of Create being (particularly) slow, you just have a lot going on in general.
2000 μs, while interestingly high, it's far from any TPS drop. You need to reach 50,000 μs to drop from 20 TPS.
@adaliszk At one point the tps dropped to 15
Could you record that with Spark and share that? The one you shared now has nothing really in it beyond the fact that you have about 5000 entities in the world, most of which are items or extra modded mobs that have nothing to do with Create itself.
After restarting, we launched 3 drills, the problem went away, apparently the problem is still in the RAM, thank you, you can close it... I'll go further to figure out what the problem could be
Within your entity tick cycle, Create has pretty much zero contribution:
Within block entities, you have quite a lot of Chute and Threshold switch load. Are your farms using chutes, but they are extremely slow in throughput, so they constantly transfer? If so, I think you should fix that.
All your problems stem from the fact that you load 2000 chunks, which in turn brings a ton of unoptimized processing and a lot of mob logic. Neither of which is really something that Create could solve alone, Minecraft itself is not meant to be loading this much off-screen logic.
To be honest, I didn't know I was uploading so many chunks. Where can I look for restrictions with an average online of 30-50 players?
Okay, lets go over some Server Hosting 101:
I can see you added 30 cores to the VM, but in reality it will never use that much. Minecraft only uses about 3-6 threads total, where the bulk of the logic happens on a single thread.
- Thread Tweak that can help with I/O, lighting, worldgen, and async tasks such as logging, networking, limited block updates, as it can increase the worker threads, but only those.
- Lithium can help with a few things like Entity lookups, several Collections and Math operations to worker threads, but that still leaves the core logic on the main thread.
- Dimensional Threads can split the main thread into several threads, but it is not fully compatible with Create and a lot of other mods that do rely on the fact that there is a tick order and shared memory on the same thread.
So, assigning more than 3-6 cores to a Minecraft server generally wasteful. What you really want is high single core performance, so that the main thread could process the load quicker. Optimization mods such as Lithium can help a lot.
With the loaded chunks, that is governed by any chunk loading methods and the simulation distance. Generally, with more than 10 players, you want the simulation distance to be low, like about 4-6. The default 8, each player would load 289 chunks, while with 4, they would load only 81.
However, with such low simulation range, you would need to rely on really targeted chunk loading for machines that players do want to be running. So you want a chunk loading solution that only loads small, selected areas.
Now, for optimizing Create for many players, your best bet is to discourage expensive behaviours:
- Disabling contraption breaking entirely as sadly that mechanic is used with many bad designs that have slow or bad collection methods which leaves items on the ground ticking.
- Bump Vault sizes larger than 20, which usually promotes people to use them even on contraptions as having fewer individual storage blocks helps to have less storage lookups.
- Promote belts and funnels for transfer by either promoting hypertransfer via pulse clocks, or decreasing the extraction timer to 2 ticks which then makes the throughput rate high enough to finish transferring quickly.
- Increase stress capacity of more compact methods such as steam engines or windmill bearings, should promote less ticking for generating power.
Mobs ticking takes 30%, while Create entities (contraptions) only contribute 0.42%:
The main Create-related workload is the block entities, which takes 17% of your TPS budget:
Your problem is that you are reaching your hardware's limits around 6000 entities in 2400 chunks:
I don't see much optimization potential here on the Create side; that 17% contribution (8.5/50ms) seems reasonable with 2400 chunks loaded for 20 people.
However, the optimization here would not address your original assumption that contraptions are the lag source, as your Spark clearly shows that multiple mob-expansion mods add extra load to entities and lookups. Lithium and similar mods may help there by offloading the lookups to the worker threads.

unrelated to the issue but do you know of any additional documentation for server hosting 101? ive been running servers for 2 years know and think that i have some stuff left to learn.
