Profiler

Profiler is a built in mod, activated via "profiler.load = true" in minetest.conf file.

Usage: "/profiler save" by a server admin. This makes a text file "profiler date-time.txt" to check out.

The file I (Thailand) got, is from 11.09.2019

The file contains summary and single part from all activated mods and may help to target lag source.

example

more_chests:                                            
 - on_joinplayer[1] ..................................

with numbers for

min µs
max µs (leads to peaks, used for rank peaks)
avg µs (lead to avg lag, used for rank B)
min %
max %
avg % (lead to avg lag, used for rank A)

avg : mean time making work for cpu
peak : short but heavy usage, maybe feel lag

results

summary

The most avg work, mean all time through the server is on is made by mods:

advtrains (32 %)
and + messecons (13 %), mean sum cpu for 2 mods 45%
+ pipeworks (10 %) = sum top 4 with 55%
+ technic ( 9 %) = sum top 4 with 65%

check the peaks out of result pages ...

conclusion

There are main just 3 mods there behaviour have to be checks / reduces to get lag down.

advtrains, with then also japan train
messecons
pipeworks

all others are minor effect to server.

I played around with profiler since at least 2 years and successful reduced lag on my server basing on profiler results.
There is a change possible in pipeworks reducing that mod about 50% of its impact.
At advtrains I have no glue, as I dont use it, as I know its impact on servers, or pick up all the not used trains of not ready lines.

-The main hard peaks are generated out from
-* [[messecons]] peaks, counted here as 100% as most strong peaks
-* [[pipeworks]] peaks, at least strong 50% strength of [[messecons]]
-* [[advtrtains]] peaks, which are still 40% as strong like the [[messecons]] peaks
-* [[technic]] peaks, have also 35% the strength like [[messecons]] peaks
-* ambience then follow with 24% hard peaks compare to [[messecons]]
