This is a simple application where you can add images from your local storage. In this application i specially add big for loop cycle in order to see how clusterization works in Node.Js.
Clone repository, run in terminall node index.js and open http://localhost:3000, add image click upload, if you want to see image in full screen you can link http://localhost:3000/show. In order to see how clusterization works you need to install autocannon:
npm i autocannon -g
Autocannon its a simple application that can send requests on you server. You can use it to write:
autocannon -d 10 -c 200 localhost:3000
Where -d - time in seconds, -c - value of connects to your server.
When you run node index.js
When you run node cluster.js
I make many tests and if we have high loaded server with many process clusterization is a good solution for us. But sometimes one main thread its better if we has a simple application you can delete for loop cycle in file server.js and run tests again. You will see that server with cluster little bit slower then one thread server.
Also i add restarting worker if we had some errors.
Run command kill (value of PID)
