An experiment at improving the performance of PaperMC.
This project uses ASM and the attach api to modify Paper classes as they are defined. Because of this paperbin can even be run on top of other paperforks!
Make sure you have read the License. Then download paperbin and run the following command using a version 8 JVM, ideally either hotspot, openjdk or graal:
java [any jvm arguments] -noverify -jar PaperBin.jar ActualPaper.jar [any paper arguments]
paperbin did lots of impovements to my server i can f***ing handle 15k entities in 4 chunks without tps drop
