How do I know how much traffic my wordpress/buddypress based social media website could hold? What to do when traffic goes up?

Right now I'm paying 5 dollars a month for hosting to godaddy.com. Although there are no users registered yet (it's closed for maintenance mode as I'm testing and buiding it), it's slower than e.开发者_如何学Cg. facebook. Does anyone have experience on using buddypress? What happens if my site blows up and draws a lot of users very fast. I guess I can get more expensive and better quality hosting, but is there a limit for buddypress based sites, especially when I'm using quite a few plugins.

BuddyPress scales quite high, so the code itself won't be a problem, even with tens of thousands of users. Your problems will probably be imposed by your host--limiting database transactions or sizes of tables--or specific themes taking a long time to render.

Firebug can be a great tool to use if you want to identify what component is causing a site to be slow. Instructions on using Firebug
