How to fix server lag | NGP Cloud Help Center

"Lag" can mean three different problems with three different fixes. Figure out which one you have first.

Which kind of lag is it?

What players see	Type	Likely cause
Everyone rubber-bands, mobs freeze, blocks reappear	Server lag (low TPS)	The server can't keep up - CPU, RAM or a heavy plugin/mod
Only some players lag; high ping in the tab list	Network lag	Distance to the server or the player's own connection
Low FPS, stuttering, but others are fine	Client lag	The player's own computer

Fixing server lag

Check resource usage in the panel next to the console.
- Memory near 100% - you need more RAM or have a leak. Restart and watch whether it climbs back up.
- CPU pinned high - something is doing too much work every tick.
Find the culprit (Minecraft). On Paper/Purpur, install spark and run:
```
spark profiler start
```
Wait a few minutes during the lag, then run spark profiler stop and open the link it gives you. The top entries show which plugin, entity or chunk is eating the tick time.
Lower the load:
- Reduce view-distance and simulation-distance in server.properties (8 and 6 are good values).
- Pre-generate the world with a plugin like Chunky so exploring doesn't generate chunks live.
- Limit entity farms and huge redstone clocks.
- Remove plugins or mods you don't need.
Restart daily with a schedule to clear memory build-up.

Fixing network lag

Make sure your server's location is close to most players - check live latency on our locations page.
Players on Wi-Fi should try a wired connection, and close downloads or streams.
If everyone suddenly has high ping, check ngpcloud.in/status.

Still lagging?

If you've profiled and the server is simply at capacity, a bigger plan is the fix - see How to choose the right plan. Include your spark report link in a ticket and we'll help you read it.

Still stuck? Open a ticket on Discord - run /ticket in any channel, pick a department, and include your Server ID or Invoice ID so we can jump straight in.
