Is this result ok ?

Start render 0.652s fully Loaded 0.535s ??

I just see you have an error:

Yep, what you have there is a page where the contents got delivered faster than the browser could throw it up on the screen. The screen capture for the various milestones (unless you are recording video) actually forces the browser to paint to an off-screen buffer which is why you see something in the Doc Complete screen shot.

As you’ve noticed, the pie charts don’t do too well when there are only 1 or 2 requests - I’ll see if I can figure out what’s going on.
