posted about this before, wondering if the comms team have any comment
whenever i'm browsing and hit a site which is incredibly slow to load, I check with tcpdump, and many times find that (whatever it says in the addess bar of my browser), it's hosted at deploy.akamaitechnologies.com
eBay uses them and is always slow for me
tonight's example is http://www.intel.com/intel/LearningSeries.htm
I know that the akamai download servers are throttled by PN, but that shoudln't affect browsing.
TOS is fine by the way (0x80)
maybe they're just overloaded ...

Hi Paul,
Download servers would be 0x60, so it doesn't sound like that's the issue.
There's a possibility that it could be the website itself.

Why are akamai download servers throttled by PN? I use ebay a lot and often get frustrated with how slow it is at times. Is this the reason?

shouldnt be as there being picked up 0x80 but then again 0x80 means nothing now days since we have learned there are rate limits placed on sum of the sig's in the 0x80 cough full line speed prioity however youtube comes back as 0x80 yet has a rate limit placed on it

OK I'm rebooting this thread as I've been listening to Test Match commentary all afternoon (Sun 2nd Aug) with no problems.
This is the "popped out" BBC player ostensibly at http://news.bbc.co.uk/sport1/hi/cricket/england/8179593.stm --> http://news.bbc.co.uk/player/emp/pop.stm
Actually according to windump I'm receiving data from deploy.akamaitechnologies.com server.
Exactly as 4pm ticked over, the stream started to buffer and stutter to the point of "unlistenability".
Of course, 4pm is the end of "offpeak" on my product.
And yep, TOS is 0x80
I'm BB+ legacy, 6500 stable rate on a clean, very solid interleaved line
So, what gives?
Paul

Hi Paul,
You'd probably be better off switching to Value or Unlimited rather than staying on Broadband Plus. Streaming (including iPlayer) on Broadband Plus does get a moderate experience at peak times when the network is busy as per this page:
http://www.plus.net/support/broadband/products/archive/bb_plus.shtml
It should play fine at the lowest resolution but probably not at any higher resolution.

ok thanks for responding Dave
I'll stick with BB+ for the time being as overall it's better value for me on my exchange for my normal type of use than the other options.
I don't use streaming that often -- and when I do it's normally fine -- I was just interested to see that it's another example of poor response from akamai servers despite being marked as 0x80. The sudden deterioration on the stroke of 4 was interesting.
It seems not all streams are equal ...
