Slow download of YouTube 1080p videos

For a while now I noticed that during peak usage hours it is slow to download YouTube 1080p videos as opposed to 720p videos.
For example this video
https://www.youtube.com/watch?v=ULHvk8PAV0o

If you right click in this video and select "Show video info", you'll see some debuging info including download speed.
For some reason 1080p resolution download at 700kbit - 3mbit, where as 720p videos download full throttle at ~20mbit.

Anyone else experience this?

I see similar behavior... At 720p, I see peaks at 50000 kbps.... At 1080p I never see it go above 2500kbps.

It's not just you its youtube itself because I see similar slowdowns on TWC Road Runner.

if 720p videos download full throttle, why would it be youtube itself? they obviously have enough bandwidth for 720p, then why not 1080p?

edit: Could it be that CV has youtube's caching proxy on their network and it caches only 720p videos, but 1080p are coming from actual youtube and hence so slow??

I have actually found oddly enough that clearing my browser cache and hitting refresh sometimes makes them load faster, sounds wierd but it works for me sometimes.

Yes, I noticed this too. 720p videos load fast but 1080p videos only get about 1-2mbps which isn't enough to play it back without stopping every few seconds to buffer.

I used to have Verizon DSL and there sometimes I got slowdowns on 720p videos when the 480p version would load fine, and sometimes I got slowdowns on 480p version when 720p version would load fine. With OOL at least 720p works consistently fast.

I don't know if this is a problem with YouTube or a problem with the ISPs or something else.

Yes there is a problem youtube is working slow I don't know why but I feel that buffering in general is working slow on optimum. I get full download and upload and it is still slow. I have tried direct connect to the modem as well as different routers its something with the network.
