Frequently asked questions

How do I start profiling my server?
Run `/spark profiler start` to begin a profiling session, then let it run while you reproduce the lag you're experiencing. When you're done, use `/spark profiler stop` to end the session and get a shareable report link.
How do I check my server's TPS right now?
Run `/spark tps` to instantly see your current ticks-per-second and CPU usage percentage. This gives you a quick snapshot without needing to start a full profiling session.
