Description of issue
I've been running vanilla minecraft on OpenBSD 7.7-current. In a new folder, I created a papermc server. There is a significant performance loss on papermc compared to the vanilla jar.
/usr/local/jdk-21/bin/java -Xms10240M -Xmx10240M -jar _server.jar_
Plugin and Datapack List
Server Plugins (0):
There are 3 data pack(s) enabled: [vanilla (built-in)], [file/bukkit (world)], [paper (built-in)]
