Lorenceo:
mercutio: speedtest.net uses unique requests for each "random image" that it uses to download, and so even if things force-cache the content, it'll just take up lots of cache space.

so you'll have a request like:

http://speed.snap.net.nz/speedtest/random1500x1500.jpg?

then a random number after the ? .. you can request the image yourself and see it just looks like random pixels.

but with the http download, you should be able to accomplish the same thing with that 100mb speed test in fremont (california) by appending ?129321039812903812 or some other random number to it, and increment it every time you do a new test.

I just tried this, with a bunch of different number strings. The MD5 of the files that it downloads are the same, and they all came in at line speed. Even when supposedly coming from Africa.

curious. i wonder if there's somethign special on random1500x1500.jpg

anyway, that's one of the reasons i say it's good to test on port 24 :)

one solution is actually have completely random data...

so if you ever get the same md5 two times in a row something is seriously screwed.

i wonder if the transparent proxy screws with ipv6 too.

Invalid option. Perhaps we shouldn't pull this thread off topic, also?

sbiddle: I'd still really love somebody who's experiencing slow speeds and has the technical knowledge to run some tests using the high priority CIR on their connection rather than just their EIR.

I'm just curious if the connection is actually meeting the specs for the UFB product which is only around the CIR, not the EIR which at the end of the day is all best effort traffic and congestion could be occuring at many points along the way.

Well Tim (quakeguy) contacted me and I've agreed to be a Guinea pig. Snap is going to send up some hardware and is going to be placed between the ONT and my network. Tim is going to run tests and hopefully get all the info he needs.

_b Snap for trying to get to the bottom of this.

*cough* Snap, you know you want to put me on 100/50MB plan while you carry out the tests :p

I've got UFB going in on Monday so will be able to compare to my DSL connection then.

No actually, I haven't heard or seen anything...

But if I were to base my experience of UFB with Snap, I would say it's not as cracked up as it's made out to be. I don't know if it's because of the ISP, or if this is a general UFB issue.

National speed is great as it can max out my connection. International however is appalling. In fact, as we speak, I'm downloading a Steam game via a CDN server at Arizona US, fluctuating between 7KB/s and bursting up to 120KB/s. Obviously I can try to change servers, but you get the point.

https://cdn.geekzone.co.nz/imagessubs/f22fd3b394c7ce4f8151f9e4d6de78ba.jpg

That 1.6MB peak was in the beginning of the download, supposedly from TelstraClear content server. It was short lived....Actually speaking of Steam, I have never really been able to get more than 2MB/s. Even on any NZ server, including Snap.

Sometimes if things are cached the download speed is excellent. However I'm almost always disappointed with international speeds. Especially for simple single threaded downloads.

Though I can't complain about the the unlimited 1am - 7am downloads. Multi-threaded downloads usually gets around 1 - 1.6MB/sec.

So it's a mixed bag, in short, speeds are inconsistent. No where near as consistent as my previous Xtra DSL. I am curious to see what Telecom will bring for UFB.

Early next year I believe.

In my experience Telecom has almost always provided a better service, in terms of the quality of speed for their DSL. I'm sure many would speak the same as well.

Totally agree. I switched from Snap to Telecom ADSL back in 2009 because of the same International speed issue as you're having now. Telecom still give consistent 1.5MB/s to the US.

That was kind of around BUBA times I think, where Telecom had seperate systems to everyone else. I think this issue is unrelated. But could be similar in behaviour.

Not really good enough to be honest is it!

Personally might just wait for Telecom to bring their UFB offering to market with what I have heard about Snap and Orcons - a very mixed bag it appears
