profiler graph question

[Element]

what does the profiler gragh even do are mean

[Wuzzy]

This is a very good question. I would like to know this, too. Apparently the graphs are made for developers and show how well Minetest performs and how fast it does things. But I don’t know what they exactly mean.

When there is a detailed answer to this question I would like to add this information to the wiki.

when i turn them on, there are four graphs but sometimes there are five but the top one come and goes
and why are they different colors

and for players that havent seen it before, press F5 twice

[sfan5]

and why are they different colors

Because you can distinguish them easier

[Element]

i thought thats what the colors were for but what do the graphs do and mean

[sfan5]

i thought thats what the colors were for but what do the graphs do and mean

There is a description above every graph

I think what Element means is what does main loop time mean and the such.

[Element]

yea...thats it

[celeron55]

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 spent in each frame for everything else than drawing.

mainloop_dtime: Total time spent per frame (mainloop_other + mainloop_draw + mainloop_sleep); FPS = 1/this averaged.

mainloop_draw: Time spent in each frame for drawing (rendering).

client_received_packets: Number of received high-level protocol packets in each frame.

Thanks!
While this answer is accurate, it is of course way too technical for the community wiki.
I guess this fits better into the dev wiki (but I don’t contribute to it because I’m not a Minetest developer!).

Thanks for explaining in detail.

Finally I found this explanation. Maybe someone can add "packets_lost", "rupd_jitter" and "rupd_rtt"?

[azekill_DIABLO]

packet lost is self explaining

the other idk

[Tomas Brod]

rtt is round trip time. The time for a packet to got from client to server and back, like a ping.
rupd is update (upd) of something (r),
jitter is how much the value jumps around,
packets_lost is how bad is your internet connection.
Important fields are the RTT(ping) and FPS.
