Evaluation of Play 2.8 API and performance using Wrk 2.

This project provides examples how to test simplest request and configure server side for better response times and minimal CPU usage.

Please, do not go further until you take a pill.

Building & running benchmarks

Build the server

sbt clean stage
sed -i -e 's/1.6/1/g' ./target/universal/stage/bin/play

Run the server

  • Corretto 8:
export JAVA_HOME=/usr/lib/jvm/corretto-8
export JAVA_OPTS="-server -Xms2g -Xmx2g -XX:NewSize=1g -XX:MaxNewSize=1g -XX:+UseParallelGC -XX:-UseBiasedLocking -XX:+AlwaysPreTouch"
./target/universal/stage/bin/play
  • OpenJDK 16:
export JAVA_HOME=/usr/lib/jvm/openjdk-16
export JAVA_OPTS="-server -Xms2g -Xmx2g -XX:NewSize=1g -XX:MaxNewSize=1g -XX:+UseParallelGC -XX:-UseBiasedLocking -XX:+AlwaysPreTouch"
./target/universal/stage/bin/play
  • OpenJDK 16 + Graal:
export JAVA_HOME=/usr/lib/jvm/openjdk-16
export JAVA_OPTS="-server -Xms2g -Xmx2g -XX:NewSize=1g -XX:MaxNewSize=1g -XX:+UseParallelGC -XX:-UseBiasedLocking -XX:+AlwaysPreTouch -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+UseJVMCICompiler"
./target/universal/stage/bin/play
  • GraalVM CE Java 8:
export JAVA_HOME=/usr/lib/jvm/graalvm-ce-java8
export JAVA_OPTS="-server -Xms2g -Xmx2g -XX:NewSize=1g -XX:MaxNewSize=1g -XX:+UseParallelGC -XX:-UseBiasedLocking -XX:+AlwaysPreTouch"
./target/universal/stage/bin/play
  • GraalVM EE Java 11:
export JAVA_HOME=/usr/lib/jvm/graalvm-ee-java11
export JAVA_OPTS="-server -Xms2g -Xmx2g -XX:NewSize=1g -XX:MaxNewSize=1g -XX:+UseParallelGC -XX:-UseBiasedLocking -XX:+AlwaysPreTouch"
./target/universal/stage/bin/play

Run benchmarks

Server need to be warmed up before to be able handle max request rate. Use option -R with half of max value for that.
