the server tps has been at 20 the whole time for the last 3 days and now suddenly tanking hard 5-15

install and use java17
odd slate
17 for 1.20.1?
odd slate
gonna just do it for server. don't see how me having java 17 is gonna effect tps :P.
odd that it's java 17. was lead to believe 1.20.1+ needs java 21
odd slate
downgrading to 17 caused the server to crash
odd slate
install and use java17
.

lyric dune

odd slate

jade crane
yeah no advice here tbh
lyric dune
i only really know to lower sim distance and keep an eye on spark
odd slate
simulation distance is enititys loaded in chunk/near player or is that server render distance?
lyric dune
you can revert the server back to 21
jade crane
my servers tps tanks fron entitys as well
odd slate
ahh usually set the view_distance to change the server view didn't know simulation distance was render
I mean i'll change it to 2 and see how it is.
just odd to me that it was running fine for the last 3 days until today
odd slate
pretty sure that's why I used 21 because it manages trash better
lyric dune
i have no idea what arguments to use for selfhosted tbh
