TPS Lag from entities or something else?
Is this from all the entities we have or from something else?

what type of profiler is this
Spark? What do you mean? It was run with
/spark profiler start --thread *these
this is pretty cool ngl
Oh yeah it's Spark. It's included with paper and purpur servers
yeah ik spark
spark isnt like that by default
yes its modded vs plugin but still
Quite a lot huh
yeah
perhaps lower your render distance from 14 to like 10-9
Remove the
--thread flagah thats why
ffs ๐ญ
I think people were mining a bunch in the nether and the netherrack drops were piling up. Could that be the cause?
For items sure, but there's still a huge amount of item frames and displays
Also the report doesn't help much, the flag
--thread is used to monitor other threads, the lag comes from the main thread which doesn't appear when using that flag afaik
Use this instead: /spark profiler start --only-ticks-over 150
Still I'm pretty sure the entities are probably at faultOkay I'll do that next time the lag starts happening. Thanks!
Not sure why spark is so weird and doesn't just show everything with one command lol
Probably will bloat the whole page
For example, theads is used when you want to monitor some specific threads (in your case shows all because you used *), in that scenario you don't need the rest
Okay here is the updated spark report with this command: https://spark.lucko.me/jiJsNehbzf

I just don't understand how some servers can host up to 50+ players just fine and our TPS tanks to 11-12 with 6 players on. If anyone has any insight I would def appreciate it. ๐
can you please make just a normal spark report with no flags
I asked them to do a spark report filtering ticks over 150
At least from the new report, seems like an io issue? I thought it might be entity lag
In this report, did you pregenerated your world?
Your host uses ssd or hdd?
This one has entity lag, you have a huge amount of item frames
I also believe having anti xray enabled in world-defauls (every world) is having a huge impact on performance, but Iโm not sure, I donโt use papers anti-xray
Itโs a pregenerated world, ssd. So you think itโs the entities? Iโll take look into xray as well
and thatโs not helpful when the median mspt is at 63
6 ticks being over 150ms over 7 minutes arenโt the cause of his server averaging 13tsp
Makes sense
Can you make a spark report without any flag like @Snow Kit mentioned? Just
/spark profiler startSure thing I'll update the next time it's lagging
Well we're not lagging anymore. Here is the spark report: https://spark.lucko.me/PPydIhWbej

Basically same number of entites. I followed the Minecraft server optimization guide a bit more aggressively and tweaked some values. Solid 20TPS with 9-10 people on
This one: https://github.com/YouHaveTrouble/minecraft-optimization
Glad you no longer have lag
Let us know if it happens again
Yh, thatโs a good guide
Thereโs also this one: https://paper-chan.moe/paper-optimization/

Thanks so much! Will take a look!
I will say, you have a bit of data packs causing lag. vanilla minecraft does have a command you can run to find out what datapack(s) are causing lag, but idk what it is off the top of my head
there was a guide now but canโt find it
