Stable TPS until triple digits -- instant drop
Hello, I own a relatively large 1.8 server. The server will run fine with around 18 to 19 TPS until it reaches triple player counts, where it will almost instantly drop to around 10 immediately, later becoming ~4 TPS as the server reaches a player count of 120 or so.
I'm really not sure what to do, and I've provided a link with my timings. Any help is appreciated!
Server has 10GB of ram but even at higher player counts it will never use above 7. I do have more ram to allocate though. I'm using velocity if that matters at all.

well, that timings report claims the issue is oversleep, which would be caused by a bad server host (or I misread the report, which is possible), but I'd also prefer a spark profile if possible
Is there any way to optimize the oversleep or is the only solution to get a better host?
Here’s my spark report: https://spark.lucko.me/VqHKgoctdP
spark
spark is a performance profiler for Minecraft clients, servers, and proxies.
is this running on oracle cloud's free tier?
Yes
yeah, so you're server's CPU is at almost 100% right now
it still seemed to occur when it’s at around 80% systemwide so I thought that wasn’t the issue
also most of the lag is coming from just players flying around
it’s survival so flying should be disabled…
Nobody is flying except me
oh I might've misread it
does that spigot fork have any packet rate limiting?
It’s imanity and I don’t think so
yeah, could be a malicious player spamming packets
I have viaversion installed and I’ve heard that there’s a packet limiting feature
Lpx didn’t support java 11 last time I checked
can you not use java 17?
It broke either the previous spigot I was using or one of the plugins, I’ll check in a bit
also, for velocity should it be running in 21?
I mean, if all your plugins work, it probably doesn't matter too much
I barely have any plugins in velocity soooo
Yeah java 17 works
i'm gonna bump this thread
i'll probably be getting new hosting but I do need a temporary fix
