Profiler

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

• Profiler 23.10.2019
• Profiler 11.09.2019

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.

Thailand, known as Festus1965 in Forum, and Thomas or Explorer on most other servers. 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.
