Spark and its profiler can be installed on a Minecraft Spigot server to gain valuable insights into its performance. By efficiently analyzing large data volumes, Spark helps identify and optimize performance bottlenecks, such as slow plugins or inefficient server configurations. This makes Spark an invaluable tool when troubleshooting servers.

Note: The Spark Profiler will only work on Spigot servers.
