Is it possible to get the network size for all loaded resources on a web page?

Question

To analyze page load performance, I need to know the total network size of all resources on the page (html, static content). Is there a way to do this on the client side using javascript?

Explanation: Data must be sent to the server for analysis, so I need access to the network size in javascript.
