[EN]Hi all !! i need some help on a problem that im having to my server ... i followed step by step the instructions of the topic that "papaditsa" made and i opened gameserve.bat and logingserver.bat correctly then when i go log into game at the phase that the screen of world selection appears (e.g. Bartz ) i press enter or Confirm button to enter but at the bottom a message appears saying that "your protocol version is different,please continue" ...!! what i have done wrong ?? and how i can fix this ?? Thanx in advantage and if you could answer me as fast as you can because its emergency :D Thanx for your time :)

“Hello, I’d like to present a short description of the server. Everyone starts equally at max level 80. The server includes a custom buffer, custom class master, custom weapons and armors, custom zones, custom teleporter, custom raid bosses, and much more. I’ll leave a link in the description for those who want to see how everything looks inside. The server is only open on weekends, and you can find more news via the Facebook link.”

1. You where subscriber 3 years ago.
2. There is no current L2jMobius 2.8 Seven Signs version. Subcriber or not.
3. You have your answer from multiple forums that more items is more delay.
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)
