I'm currently developing a web app that is built on the LAMP stack. I want to know how I can estimate how much bandwidth, storage, processing, etc. it will take when I hit a certain number of users. What are some tools I can use to make these estimates?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Use a load testing tool to test whatever equipment you have then extrapolate from there. – Chris S May 1 '11 at 4:07

I use a combination of Sargon and Systat to log processor usage, nic in/out traffic, memory usage, and storage. Then it is just a matter of correlating that data with your traffic and calculate pricing based on that information. Hope that helps!
