This is a simple node.js HTTP application that can be hosted in IIS using iisnode or self-hosted with node directly. It exposes two HTTP APIs:
GET /Customer/{customerId} will return a pre-baked JSON object with customer information.
POST /Order/{customerId} will accept and parse any JSON document in the body of the HTTP requst, and return a pre-baked array of JSON objects representing orders
git clone https://github.com/tjanczuk/webapiperf
cd webapiperf
npm install
cd webapiperf
node server.js
Then visit the URL http://localhost:8000/Customer/12.
By default the server will listen on port 8000. This can be overriden by setting the PORT environment variable before starting node.
The self-hosted configuration will use cluster to create as many node.exe worker processes as there are CPU cores on the machine. This allows full utilization of the CPU under stress.
Create a new Web Site in IIS and point it to the webapiperf directory. Then visit the url, e.g. http://localhost:9000/Customer/12.
NOTE: the application must be hosted at the root of the web site, not in a virtual directory underneath in order for the URL paths in the application to match the requests.
