Minecraft Spark Analyzer
Paste your spark profile and get automatic optimization recommendations for your Minecraft server.
- Install spark on your server and restart it (not needed on Purpur 1.19+).
- Run /spark profiler in the console or chat.
- Run /spark profiler --stop and copy the link it gives you.
These are not magic values. Many of these settings have real consequences on your server mechanics.

You can apply the recommendations above today. But if the bottleneck is a node whose CPU is choked because your provider packs too many servers onto one machine, no amount of tuning fixes it. That's when moving is the answer.
