Build

cd benchmark-base
docker build . -t atm6
cd ../jvm
docker build . -t atm6:jvm
cd ../graalvm
docker build . -t atm6:graalvm

Test

For each jvm and graalvm, run following command

docker run -it -p 25565:25565 atm6:jvm
docker run -it -p 25565:25565 atm6:graalvm

when server is fully loaded, profile by spark command

spark profiler --timeout 600

profile

World

  1. To make benchmark fair, disable all entity spawning on server.properties
spawn-animals=false
spawn-monsters=false
spawn-npcs=false

  1. Fill 144 chunks with 36,864 (12 * 12 * 16 * 16) solar panel fill

  2. Chunkload 144 chunks chunkload

Note

  • If you want to see report file, use online viewer
  • I tried to generate flat map by minecraft:flat on server.properties, but it didn't work
  • I know there will be my userid on world file, but I don't think it will cause on security issue.
  • Require more complex map that can make tps below 20 on GraalVM
