Increased secure connection latency

RE: Increased secure connection latency
Is there another way to decipher what's going on underneath the hood at these times (between DNS and Initial Connection)? I see an option on the Advance tab for tcpdump (I'll try that and get back to you), but haven't used it before in WPT. I have looked at some WireShark tcplogs from my local machine a while back - maybe the outputs are similar? I'm trying to target some optimization efforts at the connection related requests to improve TTFB, SSL negotiations times, etc. and reduce page load times further (unless you see other lower hanging fruit opportunities in the waterfall to focus on).

IE10: http://www.webpagetest.org/result/140210...4/details/ (need more visibility into connection time gaps)
IE11: http://www.webpagetest.org/result/140210...7/details/ (doesn't show much detail in waterfall or request details to understand what's going on with this browser version)
Chrome: http://www.webpagetest.org/result/140210...ils/cached (shows 1+ sec longer Fully Loaded Time in summary table vs. Waterfall or Request Details sections?)

Any guidance in applying WPO with the varying levels of detail between the different browser results listed above would be greatly appreciated.
Thanks!
