Heavy lag (Terralith issue?)
Hello, I started a fabric server some days ago on a google cloud server (16 gigs of ram, AMD EPYC 7B12) and the server has a really high MSPT and also dropping to 15-9 tps constantly and rarely being stable at 18-20 tps. We don't have any heavy mods except Terralith, Dungeons and Taverns and Tectonic, the rest are just performance mods or mods like voicechat.
For the server we just use openjdk 21 and aikars flags with 12 gigs of ram assigned to it.
Hare are some spark profiles of the server: https://spark.lucko.me/M1JkTaw8Ao and https://spark.lucko.me/d584VAbkMe

If you need any more information feel free to ask !
Also the server is running Ubuntu 25.04, but that prob doesn't matter
Ubuntu 25?
since when was that a thing
anyways
!offline
it's not the LTS version tho
I don't manage the google cloud account I just configure the server
hm yeah it is a real thing
april 2025
that's what 25.04 stands for
ye just checking rn
neat
doesn't appear to exist for 1.21.5
yeah, all your lag is just from converting chunks to newer formats
so it'll eventually go away
I hope so
btw should I use c2me?
cuz when I had it, the spark profiler said that it used like 40-50% of server time with a thread locked
it might help? not sure tbh
the server is around 18 ticks now
I could prob lower the simulation distance and call it a day
