couch-bench

Reproduction of the NodeJS vs J2EE benchmark used as a demonstration in the following article.

The setup uses two machines, an injector (using Gatling) and a server (hosting Tomcat, NodeJS and CouchDB).

Create the machines

We will use Vagrant and VirtualBox so you should have both installed on your machine.

The default configuration uses 2 CPUs for the injector and 4 CPUs for the server.

cd couch-bench/vm
vagrant up

Prepare the database

From the injector, insert 10 000 entries of 4000 bytes each in CouchDB and keep the result

vagrant ssh injector
cd couch-bench/injector
wget -O src/test/resources/data/ids.csv http://192.168.10.3:8080/couch-bench/inject/10000

Launch on J2EE

This will launch Gatling with a 10 seconds ramp (hardcoded), a 5 minutes duration (hardcoded) and 10 users (parameter, default is 1).

vagrant ssh injector
cd couch-bench/injector
mvn gatling:execute -Dgatling.simulationClass=CouchSimulation -Dusers=10

Launch on NodeJS

First, launch node on the server

vagrant ssh server
cd couch-bench/server
npm install
nodejs main.js

Then, launch the benchmark

vagrant ssh injector
cd couch-bench/injector
mvn gatling:execute -Dgatling.simulationClass=CouchSimulation -Dusers=10 -DisNode=true

Other useful commands

To retrieve all the ids you can call wget -O ids.csv http://192.168.10.3:8080/couch-bench/all To check that CouchDB is working do curl http://192.168.10.3:5984/
