I have a dedicated (really dedicated. Not VPS) with the following configurations: 2x Intel Xeon L5420, 16GB RAM, HD: 2X 1Tb, Traffic: 10TB, Usable IP: 1 or 5 Free, Up Link: 100Mb, UpPort: 1000Mb, Anti-DDOS Protection, Windows Server 2012.
I plan to run a High Five (H5) L2JSunrise server.
My question is: How should I allocate and configure my memory for gameserver to support as many players as possible?
and how many online players will it support without lag or crashes ??
Note: I will use Full GEODATA
here is my GameServer.bat settings:
@echo off
title Game Server Console
color 0B
:start
echo Starting L2J Game Server.
echo.
java -server -Dfile.encoding=UTF-8 -Xmx3G -cp config/xml;./../libs/*;core.jar l2r.gameserver.GameServer
REM NOTE: If you have a powerful machine, you could modify/add some extra parameters for performance, like:
REM -Xms1536m
REM -Xmx3072m
REM -XX:+AggressiveOpts
REM Use this parameters carefully, some of them could cause abnormal behavior, deadlocks, etc.

if ERRORLEVEL 2 goto restart
if ERRORLEVEL 1 goto error
goto end
:restart
echo.
echo Admin Restarted Game Server.
echo.
goto start
:error
echo.
echo Game Server Terminated Abnormally!
echo.
:end
echo.
echo Game Server Terminated.

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)
