Re: Support for page/resource size

+1 the need for resource sizes. 

Beyond this, why not just include everything in the HAR specification( http://www.softwareishard.com/blog/har-12-spec/)  so we can generate waterfalls and debug performance issues with the current HAR-based toolset?

Thanks,

Peter

But, personally, if I was pushed, I would probably go with total request size. I think this would fall inline with expectations - as I think that's what most dev tools show and tells me the true size of the request if I care about the network "cost".
