The profiler graphs show the performance of Minetest in a more detailed fashion. This information is useful for engine developers. The profiler graphs are shown when you hit the debug key (F5 by default) twice.

The following graphs are available:

  • rudp_rtt: ???
  • rudp_jitter: ???
  • packets_lost: ???
  • num_processed_meshes: The engine generates geometric meshes from MapBlock data for drawing. This is the number of those meshes that finished generating in each frame.
  • mainloop_sleep: If the game runs at a faster rate than wanted_fps, a sleep is inserted into each frame after drawing in order to not consume excess resources; this is that sleep time in seconds.
  • mainloop_other: Time (in seconds) spent in each frame for everything else than drawing.
  • mainloop_dtime: Total time (in seconds) spent per frame (mainloop_other + mainloop_draw + mainloop_sleep); FPS = 1 divided by this, averaged.
  • mainloop_draw: Time (in seconds) spent in each frame for drawing (rendering).
  • client_received_packets: Number of received high-level protocol packets in each frame.
