1) First define what “lag” means

Players use “lag” to describe different issues. If you do not identify the symptom correctly, you will fix the wrong thing.

• TPS lag: blocks break late, mobs freeze, redstone delays, rubber-banding.
• Network lag: timeouts, disconnects, chat delays, inconsistent movement.
• Client FPS: one player’s computer struggles even if the server is fine.

2) If TPS is low

Common causes include high view distance, expensive chunk generation, entity overload (farms/villagers), and heavy plugin/mod logic. Change one variable at a time and retest.

3) If TPS is fine but players lag

Look at network quality: packet loss is often worse than high ping. Compare multiple players in different regions and observe patterns (only one player vs everyone).

4) Avoid the “restart myth”

Restarts can temporarily mask memory pressure, but they do not fix overloaded tick workload. Fix the cause, not the symptom.

5) PortalMine benefit

A clear panel and reliable status visibility reduce troubleshooting noise so you can focus on logs and controlled testing.

Bottom line: diagnose first, then adjust one variable at a time.

Practical checklist

• Write down your goal (friends-only, public community, modded pack, minigames).
• Start with the simplest configuration that meets that goal.
• Document every change you make (date + what + why).
• Test with a small group before you announce it publicly.

Common mistakes to avoid

• Installing too many plugins/mods at once, then not knowing what caused problems.
• Changing ten settings at the same time instead of one variable per test.
• Giving operator access too widely (a fast path to griefing and accidents).
• Running without backups or relying on “I’ll remember to back up later”.

PortalMine tip

If you’re using PortalMine, keep your onboarding simple: link your players to one message that includes the server address, version, and a short rules page. Then link the FAQ for quick fixes and the Status page for maintenance updates. Clear, stable information reduces “support spam”.
