What's the deal with CDN speeds on Snap? Downloading from ATI I can only get a max of ~800KB/s (wget) and 600KB/s (Chrome) from a single TCP stream. Yet, from some random place in USA I can get near line speed

On Telecom I was able to achieve line speed from the ATI CDN, both those CDN links seem to be served out of Australia and seems to be the odd packet loss

well i got < 80k/sec from it when i originally tried it.

fwiw, chrome 28+ on linux is blindingly fast in actual browsing. for some reason it's way faster than 27.

and 8000kb/sec doing it in the US. then scp back :)

to me it looks like the normal australia issues.

it seems a lot of isp's have been having problems with australia traffic recently.

orcon, callplus, snap, telstraclear, vocus, have all had issues within the last couple of years.

the real solution would be more of these australia cdn's getting nz nodes.

Single threaded:
- 30mbps to the ATI download
- 2mbps to the Chrome one
From one of those other named ISPs above of course

the vocus ping to dl.google.com is 450 msec, but is till got 500k/sec... hmmm..

although it did say 286 on a google sydney hop.

that's with ipv6 (which it defaulted to). with ipv4 it was only 200k/sec.

Something I've noticed is there's both IPv6 and v4 involved with these downloads, I see above the wget downloads are connecting over IPv4 but have you possibly got v6 enabled on your network?

This might explain why I get buffering issues on crunchyroll which is served via cp150757.edgefcs.net?

I have ipv6 disabled

michael.. i think you have a local cache.. i very much doubt you got 100mb/sec average to a US node of www2.ati.com in 1.8 seconds.

although it's nice that you get directed to US rather than AU.

not necessarily related, that ip resolves to nz akamai for me.

Hah, this was actually done off one of my servers at Hurricane Electric (only because I had a SSH session open) - I was more or less testing via an IPv6 host if this was possibly the case. It's not, looks like one of the following:

- The OP's DNS is not set to Snaps DNS servers, causing it to resolve to a CDN server not close to the OP's location (overseas)
- Snap ain't doing things right and something is angry.
