Spark - Server, Launcher FPS Booster Mod For Minecraft 1.20.4, 1.19.4
Spark 1.20.4-1.19.4 is a set of features to improve the performance of launchers and servers. It also has a set of tools that can easily diagnose current problems. You will also see the number of ticks and CPU usage.

Additionally, the mod generates entities that are attached both for the player and for mechanisms that can optimize the processes taking place around, which significantly reduces the load on the server.
You will also have a huge number of commands that are somewhat similar to server ones. You will be able to create profiles, add user rights, unload dumps to find the source of problems, test the CPU load depending on the built mechanisms, and so on.


  • /spark profiler start to start the profiler in the default operation mode.
  • /spark profiler stop to stop the profiler and view the results.
  • /spark profiler info to check the current status of the profiler.
  • /spark health – The health subcommand generates a health report for the server, including TPS, CPU, Memory and Disk Usage.
  • /spark ping – The ping subcommand prints information about average (or specific) player ping round trip times.
  • /spark tps – The tps subcommand prints information about the servers TPS (ticks per second) rate and CPU usage.
  • /spark tickmonitor – The tickmonitor subcommand controls the tick monitoring system.
  • /spark gcmonitor – The gcmonitor subcommand controls the GC (garbage collection) monitoring system.
  • /spark heapsummary – The heapsummary subcommand generates a new memory (heap) dump summary and upload it to the viewer.
  • /spark heapdump – The heapdump subcommand generates a new heapdump (.hprof snapshot) file and saves to the disk.
