Gap in TLS connection/handshake

[rudydude]

Hi Patrick,

What a great site and healthy forum! I've been following for a long time, but am only now making my first post.

I always am seeing gaps in my initial file request. For example:
http://www.webpagetest.org/result/160311...1/details/
http://www.webpagetest.org/result/160311_02_14W8/

Could you provide any details as to what's happening? We're using http2 with OCSP stapling, but still getting long TLS connections/handshakes.

I have also read in other user posts, you mention to look in firefox for more details about the gaps/SSL. I can't seem to find where these details are in FF. Is this in the Firefox developer edition? Is it the standard Network view (because here, I see the same level of detail as what's on WPT)?

Any other recommendations you can make on quick glance, including SSL?

I appreciate the assistance!
