Fixing lag & low TPS

Updated 4 Nov 2026

Is it the server?

  • Blocks break then come back: server lag. Keep reading.
  • High ping, only some players: their internet.
  • Low FPS but blocks break instantly: their computer.

Check the numbers

Type this in the Console:

Console
tps
mspt

TPS should be 20. MSPT should be under 40. Over 50 means the server cannot keep up.

Lower the distances

This helps the most. In server.properties, set:

server.properties
view-distance=8
simulation-distance=6

Do not go below 4. Restart after saving.

Find the cause with Spark

Install the Spark plugin. While it lags, run:

Console
spark profiler start --timeout 60

Open the link it gives. The widest bars show what is slow. Big mob farms and hopper chains are common causes.

Restart every day

Add a daily restart on the Schedules tab at a quiet hour. It clears memory plugins do not give back.

Problems

TPS is 20 but it still feels laggy

That is network lag. Ask players for their ping.

It lags when one player joins

Usually a farm or redstone in their base. Profile while they are on.

It is still slow

Open a ticket with a Spark link. It helps us a lot.
