I have an Idea but lack a few skills, can you help?
Idea: Mining
what is needed: Npc = Looks like a crystal, it is half as high has a character, drops items from soul ore, spirit ore,
crystals, and other items. also there is don't lvl crystals for higher lvl character, the higher
you are the higher the skill you need.
New Item = Mining ore, used for refiner to get other items. other items can be used to lvl mining axe.
Refiner = an item theat when clicked, it take 10 mining ore and gives you back other items, as it refines you will
see a breath bar come up almost like a count down, same as when you craft soulshots.
Mining skill = can not mine with out it. as you go up in lvl you can get high mining skill to help you mine better
and faster.
Mining axes = Different grades of mining axes, works the same way as weapons.
Heres my problem, I can make new items, new npc's, new axes.
what I can't do, can't make the npc that is a crystal half the size of a character. ( size)
can't do the skills, or the refiner.
So if anyone out there know how to do this it would be a great idea and we both could get alot of use out of it, as well as many others. I'm still learning how to mod textures and also working with utx, but I have along way to go. please help me :)

1. Optimize Packet Serialization
Look in ItemList.java or wherever the inventory packet is constructed.
Instead of building the packet with inefficient string concatenation or repeated allocations, use a preallocated buffer and avoid creating new objects for each item.
Mobius sources are Java-based, so profiling with something like VisualVM or YourKit can help see where most time is spent.
2. Avoid Sending the Full List Each Time
Modify the server to send only changed items (diff packets) when the inventory window opens.
Some newer forks implement this as “lazy loading” or paged inventory so the client only loads e.g. 100 items at a time.
3. Limit the Inventory Size Per Page
Instead of showing all 500 slots at once, split the inventory into pages/tabs (100 slots each).
When the user switches a tab, send only that page’s items.
This requires some client-side editing, but it’s the most user-friendly long-term fix.
4. Database & Cache Optimizations
Ensure your items table is indexed by owner_id to make the query for player items fast.
Cache item templates and static data so they are not reloaded every time the inventory is shown.
⚠️ Things to Keep in Mind
Increasing slots from 80 → 500 does not just change a number — it multiplies the workload for packet building and UI rendering.
You can’t fully avoid some extra cost with 500 items, but you can keep it under a few milliseconds if you optimize how and when the data is sent.
i think it's the auto sorting of the interface that sucks, check InventoryWnd script in interface.u, or completely disable the request item list packet when toggling the inventory window (also in InventoryWnd script or similar name)
