Vert.x EventBus and TCP Bridge for Node.js Benchmark

This is a simple benchmark what overhead gives use of Vert.x EventBus as a medium for answering the request.

Start Vert.x Event Bus with TCP Bridge

export JAVA_OPTS="-Xms2m -Xmx16m"
./node_modules/.bin/vertx run vertx-tcp-eventbus.js

Changing the memory constraints is optional step.

Start Express REST Server

node server.js

Start Event Process

node processor.js

Verify that endpoints respond correctly

curl http://localhost:3000/direct
curl http://localhost:3000/viabus

Simple benchmark

Install Apache Benchmark and then run:

ab -n 10000 -c 10 http://localhost:3000/direct

ab -n 10000 -c 10 http://localhost:3000/viabus
