An experiment at improving the performance of PaperMC.
This project uses jvmti to modify Minecraft classes at runtime. Because of this paperbin can even be run on top of modified versions of paper.

Note: It is highly recommended to run PaperBin on Java 15 using ZGC and large pages for best performance.
Download the latest 1.12.2 release from Paper's website.
Go to the releases and download PaperBin.jar as well as the relevant native library for your platform (dll for windows, dylib for mac, so for linux). The following commands will be for the linux native library, adapt them for your one.
java -jar paper-1.12.2-1618.jar
java -agentpath:libJvmClassHook.so -jar PaperBin.jar cache/patched_1.12.2.jar
The first command should exit with an error. If it does not then quit it yourself once it has finished starting up the server.
paperbin did lots of impovements to my server i can f***ing handle 15k entities in 4 chunks without tps drop

paperbin runs great for a server with 100+ players and wont affect breaking blocks or eating that much when the tps is low would recommend
