Frequently asked questions (FAQ)
What is a good TPS?
20 TPS ideal. Below 18 noticeable, below 15 heavy lag. Check with /tps or Spark.
Which view distance?
Often 6–8 for survival. Keep simulation distance lower than view distance.
Too much RAM harmful?
Yes – oversized heap → longer GC pauses. Right-size (e.g. 6–10 GB) + Aikar flags.
Plugins causing lag?
Common. Use Spark/Timings; update or replace heavy plugins.
Paper or Purpur?
Both Paper-based. Purpur has more tunables; verify plugin compatibility.
