Example node project with nginx, haproxy, and pool-hall

Example nginx, haproxy, pool-hall, node application

Running

This is designed to work on linux systems where you have node, npm, haproxy, and nginx installed, ideally from your distro's package manager of choice.

Make sure you have ports 9000-9005 open

nginx

nginx -c nginx.conf -p ./

haproxy

haproxy -f haproxy_example.cfg

node example_app

npm install
npm start

With this you should be able to make requests on http://localhost:9000/health and see 'OK'

haproxy load balancing

Hi,

I've benched the haproxy configuration in front of 2 nodes, and the requests were not load balanced. To make it work, I had to change the load balancing algorithm to leastconn.

Running load testing on this setup is slower than running directly on node worker

Hi,

First of all thanks for the example and the great article.
I configured the project and tried to run some load testing tools (siege, autocannon) on my machine to see the difference, but I actually noticed that it's much slower with the nginx+haproxy+cluster setup than running directly on one single worker instance.

autocannon localhost:9000/health caps at around 200 req/s
autocannon localhost:9002/health caps at around 5110 req/s (the worker process)

Did I misunderstand something or is it a problem of my computer?

Thanks
