How do you do Load Testing and Capacity Planning for Web Sites
I'm planning to create a "voting tool" to help votation in a conference of my NGO.
My idea would be to create a small app with node.js + mongodb for server and websocket for pushing to the various clients.
My machine is a not so young macbook pro 2.33 GHz, 2GB ram 667Mh. Is it powerful enough to support a server+db for, let say 40-50 machines?
Is the wi-fi router inside (airport) enough or is better to use an external router?
