Here's a spark profiler
more stats
you dont wanna do that
anything above 16GB does more harm than good
we did recently upgrade from 16b to 32gb
because it was lagging
but now it's worse
thr server will only utilize what it needs
so even if u put 30GB it won't use all of it
and anything above 16GB usually does more harm
it was at max earlier
before we bought the thing and the process kept being killed
is that only to the minimum usable ram?
Are you using any Aikar flags on startup?
Nope
bruh
that's a problem xd
Isn't Aikar's flags for paper
crap, forgot to mention this was forge xd

honestly if you were to use like 30gb of ram you wouldnt want to use aikars flags as it uses g1gc
but yeah, 12-18gb is around the max you should allocate
you should also consider pregening the world with Chunky
world is already pregenned
ah, that's the lagspikes
because I used them and now it's just lagspiking
was there a reason you upgrading other than just "lagging", were you getting an oom error

My server is using too much memory
My panel says my memory usage is high all the time.
Your server runs in the Java Virtual Machine (JVM), which has significant overhead & tries to effectively use ALL of the memory assigned to it.
Memory usage from "htop", Task Manager, or your server panel is the total consumption of the JVM, not just your server.
My server is lagging & I think it's memory related.
It's much more likely that you are bottlenecked by your CPU, disk, or some inefficient mod/plugin.
Rule of thumb, servers should have anywhere from 4GB to 12GB of memory, with 8GB being the 'sweet spot'.
If you're heavily modded, add 4GB to that.
Too much memory can be a bad thing. Don't exceed these caps unless you really know why you're doing it.
Troubleshoot your server the right way: use Spark & send us a report.
My server is randomly terminated unexpectedly.
Setting your server to use 8GB does not mean that Java won't exceed this amount.
As a rule of thumb, allow your system/container about 1-2GB (possibly more) overhead outside of the server.
If you're on Linux & can SSH into the system, check your kernel logs. They will report any incidents of OOM.
I want to use swap to allocate more memory.
Don't. Swap is not free memory and using it can negatively impact performance.

how do I check kernel logs?
tail -f /var/log/kern.log
