Every now and then I like to look through the test history to see what kind of opportunities for improvement there are. This morning I saw what looked like the most painful example of why persistent connections should be used: http://www.webpagetest.org/result/090417_1CQ5/
74 https requests all without persistent connections or expires headers (and in this case hosted in Japan and tested from the US). Now granted, I doubt you’ll be ordering pizza from a Pizza Hut if you’re not somewhat close to their location but even just negotiating all of those extra SSL connections has to hurt.
As it is, it took 34 seconds to load over FIOS for the first view and only came down to 24 seconds for the repeat view (which was only 37KB of data!!!).
Hopefully it’s just a testing harness since it’s not on the pizzahut domain and they get it fixed before the deployment but OUCH!
