Overview

Benchmark host machine

For benchmarking we are using DigitalOcean's CPU Optimized Droplets:

  • JMH version: 1.21

  • VM version: JDK 1.8.0_181, Java HotSpot(TM) 64-Bit Server VM, 25.181-b13

  • VM options: -Xms1G -Xmx2G

  • Warmup: 10 iterations, 10 s each

  • Measurement: 20 iterations, 10 s each

  • Timeout: 10 min per iteration

  • Threads: 1 thread, will synchronize iterations

  • Benchmark mode: Throughput, ops/time

The results

Multi client tests

The installation consist of a server node at separate thread, which echoes the messages and N-threads-clients, which pitch the messages and receive it back.

Mailbox to mailbox

In this test we have only one node and two mailboxes which send the message to each other.

How to setup the environment

  1. Add Java repository:
$> sudo add-apt-repository --yes ppa:webupd8team/java
  1. Update and upgrade the distro:
$> sudo apt-get update --yes && sudo apt-get upgrade --yes
  1. Install Git, Java 8 and Maven:
$> sudo apt-get install --yes oracle-java8-installer git maven
  1. Clone the repo:
$> git clone https://github.com/appulse-projects/encon-java.git

How to run the benchmarks

  1. Go to the project's root:
$> cd encon-java
  1. Build the project with only needed dependencies:
$> mvn clean package \
     -DskipTests \
     -Dgpg.skip \
     -Dfindbugs.skip=true \
     -Dpmd.skip=true \
     -Dcheckstyle.skip \
     -Dmaven.test.skip=true \
     -pl benchmark -am
  1. Run the tests
$> nohup java -Xms1G -Xmx2G -jar benchmark/target/benchmarks.jar > job.logs 2>&1 &

One-liner

$> sudo add-apt-repository --yes ppa:webupd8team/java && \
   sudo apt-get update --yes && sudo apt-get upgrade --yes && \
   sudo apt-get install --yes oracle-java8-installer git maven && \
   git clone https://github.com/appulse-projects/encon-java.git && \
   cd encon-java && \
   mvn clean package \
     -DskipTests \
     -Dgpg.skip \
     -Dfindbugs.skip=true \
     -Dpmd.skip=true \
     -Dcheckstyle.skip \
     -Dmaven.test.skip=true \
     -pl benchmark -am && \
  nohup java -Xms1G -Xmx2G -jar benchmark/target/benchmarks.jar > job.logs 2>&1 &
