Can eValid measure the download times and sizes of individual page components?

You can get this kind of data by setting the output level of your playback to "detailed" (you do this in the Settings).

Then, the EventLog at playback time will show you the name of every page component and how big it is and how long it took to download. eValid does this by actually instrumenting the part of the browser that launches separate threads that retrieve each HTTP/S page component, and then noting the time and byte-count each one processed.

By the way, if you add up the times for all of the components it will usually be the case that the total time exceeds the amount of time the page acutally takes to load, which might not make sense until you appreciate that the browser can run several of these individual "go get this HTTP/S item" processes in parallel. Parallelism like this vastly improves browser performance.
