After CISP sorted out their international problem I had 0 issues with twitch. I tried multiple channels too, IEM, Giantwaffle, Quickybaby, Skill4ltu, SherrifELI, Shroud. All source, no buffering. I will test again tonight though. Holding thumbs it stays like this.
I've also had major issues with downloading destiny in the past too. 3mb is the usual but I've become pretty suspect of the battlenet launcher. I've tested and destiny will be slow as hell but if I change over to download diablo 3 or Heros of the Storm it flies. It could be something with how bungie compress their files vs how blizzard do it. I've also had issues where the battlenet launcher will just consume 90-95% of my 7700k CPU for just no reason to the point where I thought it was bitcoin mining my pc. A quick google search told me I'm not alone in that issue so I have no idea whats going on with battlenet.
