Gratuitous plug, my startup, https://rasterize.io https://rasterize.io, will give you most of the information in the chrome timeline, for every single visitor to your site. It also analyzes the page and detects a lot of these warnings, and alert when you introduce things that slow the page down. It's in beta, but contact me if you're interested.
