Navigation and Resource Timing provides timing data for the fetch, but currently there is no interoperable way for the server to communicate own timing information to the client. For example:

• What steps were taken to generate the resource, and how long each took. Many sites already embed this type of information via HTML comments - e.g. wordpress emits <!--Page generated in X.X seconds.--> , and many sites provide more detailed stats (cache, db, generation) to enable performance debugging.
• If proxied, where was the time spent - e.g. time to fetch from origin, time to process response, etc.

Instead of relying on arbitrary HTML comments, we can define an HTTP header that can be used to send key-value pairs in a well defined format. Making this data available via a well defined interface would...

• Allow UA and other developer tools to automatically annotate appropriate timelines.
• Allow analytics vendors to gather this data for operational analysis.
• Allows proxies and CDNs to append custom timing d

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!
