Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I currently have a VPS that is consuming a ton of outgoing bandwidth and I am trying to drill down to where this may be coming from. Does anyone know of a logical way to go about finding out which pages on the site are consuming the most outgoing data. We have done a ton of front-end optimizations to the site and our google page speed rankings ar 85% so I feel we have done a pretty great job at optimizing the site for speed.

Can someone lend some insight on how they have made similar optimizations?

You can analyze the access log files from your nginx, provided that you have different log files for different vhosts. Then you can write a simple script which extracts the important data from the logfiles. Maybe you can even find some suitable plugin for munin.
