Up until this point I've been doing it by hand (Chrome Inspector Network panel + HAR exports) thinking at some point I'd automate. That day has come but I'm having trouble finding an easy way to do it so I thought I'd ask the LRUG omni-mind.

I think that if you load pages in phantomjs (eg via poltergeist) that you can get all the data that goes into the network activity panel

Not much usable timing data in that but may just need a bit of hacking.
