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
