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)

RatePartySp = 1
RateConsumableCost = 1
RateDropItems = 1
RateRaidDropItems = 1
RateDropSpoil = 1
RateDropManor = 1
RateKarmaExpLost = 1
RateSiegeGuardsPrice = 1
# Modify the rate of reward of all extractable items and skills.
# Default: 1.
RateExtractable = 1.
# Hellbound trust increase/decrease multipliers
RateHellboundTrustIncrease = 1
RateHellboundTrustDecrease = 1
# Quest Multipliers
# Warning: Many quests need to be rewritten
# for this setting to work properly.
# Quest item drop multiplier
RateQuestDrop = 1
# Exp/SP reward multipliers
RateQuestRewardXP = 1
RateQuestRewardSP = 1
# Adena reward multiplier
RateQuestRewardAdena = 1
# Use additional item multipliers?
# Default: False
UseQuestRewardMultipliers = False
# Default reward multiplier
# When UseRewardMultipliers=False - default multiplier is used for any reward
# When UseRewardMultipliers=True - default multiplier is used for all items not affected by additional multipliers
# Default: 1
RateQuestReward = 1
# Additional quest-reward multipliers based on item type
RateQuestRewardPotion = 1
RateQuestRewardScroll = 1
RateQuestRewardRecipe = 1
RateQuestRewardMaterial = 1
# List of items affected by custom drop rate by id, used now for Adena rate too.
# Usage: itemId1,dropChance1;itemId2,dropChance2;...
# Note: Make sure the lists do NOT CONTAIN trailing spaces or spaces between the numbers!
# Example for Raid boss 1x jewelry: 6656,1;6657,1;6658,1;6659,1;6660,1;6661,1;6662,1;8191,1;10170,1;10314,1;

Please someone can help me?
