That looks like your problem right there. Have you tried connecting via ethernet instead and seeing how Youtube performs? On 3/6/2013 10:09 PM, Min wrote:

Why are your response times so high at your first hop? Are you maxing out your connection or connected to your router over wireless?

In my case, I suspected two things.
1. congestion (verizon over subscribed) 2. packet out of order (high packet drops in alternet-google could be a symptom of multipath)
Not sure which has bigger performance impact to youtube.

The 1st one gets slow at XO and the 2nd and 3rd get slow at Sprint.
Now the interesting one with XO is that it is routed in a /30 that is assigned to Google by XO.

I just got home and tested with quite a few 1080p videos. No issues over my Hurricane Electric IPv6 tunnel. I did notice frequent stops to buffer on my FiOS IPv4 connection. I have a 50 Mbps down connection and don't even come close to maxing it when watching Youtube videos.
