akamai speed cap lower than normal?

Trying to get nvidia drivers and download speed is capping to maximum of 30kB/s and usually stalling.  I have tried with Opera/Waterfox with no change and wireshark shows its on the correct Traffic Priority of 0x80

Re: akamai speed cap lower than normal?

I am also having this issue.
Nvidia drivers and Adobe software.
Addresses that seem to be giving slow dl speeds:
uk.downlaod.nvidia.com
us.download.nvidia.com
ardownload.adobe.com

Major speed issues downloading on PS3, router logs show
zeus.dl.playstation.net
which resolves to Akamai IP addresses

Thanks Matt.
It also seems to be affecting windows updates (those that are on Akamai servers).

Re: akamai speed cap lower than normal?

I can confirm I am seeing the same behaviour on a fibre connection from Plusnet. Feels like very aggressive traffic shaping as it starts out (albeit very briefly) quickly and then very rapidly reduces down to 0bytes/s

If its any help, I can stream HD video via BBC iPlayer without issue from the Akamai servers.

Re: akamai speed cap lower than normal?

no url's supplied for others to test.
I just tried http://uk.download.nvidia.com/Windows/350.12/350.12-desktop-win8-win7-winvista-64bit-international-w...
It is crawling at a very low speed.

I am on a unlimited product so why am I rate limited?
downloading via a proxy gives a speed about 90% of line speed.
oh dear.

Having the same problems with Nvidia's downloads, stays around 15-30kb/s and then stalls completely. I also noticed that Malwarebytes took unusually long to update as well.
Hopefully this gets sorted quickly.

Re: akamai speed cap lower than normal?

the problem still exists now incase you wasnt aware, so seems it has no relation to peak time.

http://uk.download.nvidia.com/Windows/350.12/350.12-desktop-win8-win7-winvista-64bit-international-w... gives the attached trace, no change today still can't download it
edit: due to get fibre tomorrow to complicate things, if trying to do a remote test with my connection
