           Summary: Inspector resources should support "parse time" for
                    scripts
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Web Inspector
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mtakacs at yahoo.com


The Inspector's Resources panel graph shows the time it takes for a particular
script to download broken down into request and load.

There's a visual distinction being made at the start of the request (partially
opaque bar) and then the bar goes solid (once the data starts coming in?).  It
would be interesting to have a post-loaded bar (perhaps partially opaque on the
end of the request) that would account for the time to parse the script before
it's available for execution.   

This is only really useful with large application-level JS downloads or batched
JS downloads (via something like YUI's loader that makes one request for all
the scripts on the page).  

ASCII visualization

mega.js:   ..........OOOOOOOOOOOOoo

where "........" represents the current pre-bar
where "OOOO" represents the current solid bar
where "oo" represents the enhancement measuring the time from "network download
completion until JS parse completion"
