OS Name/Version: Windows 10
Product Name/Version: AMP Release “Triton” v22.214.171.124
I host a Minecraft server for myself and friends to casually use, rarely more than 5 people on at a time. We recently decided to start a new server, so I opened up the Instance I use for Fabric Minecraft, update it to the latest AMP version, upgrade to the latest Minecraft version (1.18.2), and start the server.
The last time I ran this instance, the RAM usage when the server had no players online was around 2GB of 6GB. Now, it reads as 18GB of 6GB. When logged on, chunks struggle to keep up when exploring. The only thing that has changed, from what I can tell, is the AMP version.
In the “Additional Java Arguments” I have the following:
-XX:+UnlockExperimentalVMOptions -XX:+UseZGC -XX:+ZProactive -XX:ZCollectionInterval=600 -XX:+UseLargePages -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:+ParallelRefProcEnabled -XX:+PerfDisableSharedMem
When originally running this instance, it significantly lowered the RAM usage. Now, it increases it to 18GB.
With no arguments, the server runs at 5GB of 6GB, although still a bit slow to load chuncks. Removing “-XX:+UseZGC” has the same affect.
Is there a fix for this? I think I’ve read that downgrading it’s possible, but is it possible to start an instance of an older version?
