Understanding Lag Spikes Lag spikes occur when one or a few game ticks take significantly longer than average to execute. They might: Happen frequently (e.g., once every 20 ticks). Occur rarely (e.g., once every minute). Be tied to specific player actions or server events. Lag spikes can be challenging to diagnose because typical profiling averages out the data, masking the spikes. However, Spark offers tools like /spark tickmonitor and /spark profiler to pinpoint these issues effectively.
