Quantum Quarry's #1224

Open Sitherious opened 7 years ago

Sitherious commented 7 years ago

ive noticed on our server, that if there are any more then 60 quarries running it kills the tps we have had to limit the usage of this sadly and i was curious if there is any fix to this. we have never had an issue with the old ender quary

i can get the sponge timing reports if you like. i also created a test server to test it with nothing else in the world made 30+ quarrys and then the tps goes down, i dont know if the quarry does block updates or whatever but this can easly be reproduced if you make 30+ quarrys fully power them

We have banned the quantum quarries from our server not worth the headache there are much better options than this. We run sponge on all 3 of our servers and have had no issue with lag since the removal of the quarries.

It's because they actually spawn a new dimension with random biomes, and then actually mine out that dimension. Check out this comment from Reddit: https://www.reddit.com/r/feedthebeast/comments/57we8b/discussion_i_personally_find_the_new_extra/d8vv1cd/

I like that the new quarry is "laser style" in that it doesn't actually mess up my overworld. I hope it can remain the same sort of style while fixing the performance issues.

The dimension it creates has 0 lag thru the profiler, it's the quarry itself. I will set my setup back up and paste the profiler info sometime tomorrow after I wake up.

https://paste.ubuntu.com/23776400/ <------ test server running 20 quarries, tps still 20

https://paste.ubuntu.com/23776506/ <---- test server running 60 quarries, tps 16.24

each new quarry now drops the tps by 1 full %

I have noticed that the tps drop per quarry is worse if it is separate users building them. On the test servers one user produced no appreciable results till higher numbers as Sitherious stated, but added more users making the quarries hastened the tps drops. I tested with multiple ram just in case at 4GB 7GB and 10Gb. Dedicated cpu not vps or crappy hosted btw. This issue is still present in the current 1.10.2 version (in beyond pack with prompted my testing)
