In the end it comes down to how much bandwidth ISPs buy and how they carve it up. At I have a 3megabit link though telecom global gateway and I can tell you it's nothling like a 3megabit adsl connection. I mean it's actually 3megbit of dedicated bandwidth. so long as the site you are connecting to (outside NZ) allows you to download at say 768kbps that's just how fast it will go. (assuming their ISP and any networks in between are not limiting the speed; due to my experience at work I don't think this where the problem is).

It's simple
!

"As fast as your line will go" ??? BS!
It's got nothing to do with your line(except in cases where it does) just look at national speeds, No your line is working just fine!

"As much bandwidth as xtra decides to allocate for x number of customers" More like it!

Now who is going to tell me that xtra are providing enough international bandwidth to it's customers?

Find and repalce xtra for what ever ISP you like, some are better than others at any given time.

But what type of latency do you have over your connection and can you use your entire link up with 1 TCP download?

Do you download from windows XP, Vista, Mac, Linux? (The OS affects the thruput you will get)

All these things + a few more affect the single thruput you can get on a connection.

If you increased your link to say a 10M connection. Would you expect a single download to be able to max our the circuit? I don't think so.

Thanks

Yeah I hear what saying but listen we're talking about downloads that are so slow that the number of tcp connections doesn't come into it. I'll use the my favourite example.

AT HOME  ADSL  Conenction ("AS FAST  AS MY LINBE WILL GO" (2.5mbps))

Single tcp connection download (FireFox) from nz debain(600mb iso) mirror speed: 250 kilobytes/sec

Single tcp connection download (FireFox) from auz (optus just accross the ditch) debain(600mb iso) mirror speed: 32 kilobytes/sec

AT WORK 3 megabit global gateway connection

Single tcp connection download (FireFox) from nz debain(600mb iso) mirror speed: 250 kilobytes/sec

Single tcp connection download (FireFox) from auz (optus just accross the ditch) debain(600mb iso) mirror speed: 250 kilobytes/sec


Simple!
My ISP didn't allocate enough international bandwidth.

Let me add the fine print xtra forgot.

"As fast as your line will go"*

*National traffic only. International traffic limited to 256kbps

Simple!

Your work is probably on fibre or some other connection where they have dedicated international bandwidth. ADSL bandwidth is shared between other users on the network. The simple reasoning behind this is - Cost. International traffic is around $500 per meg. If you want a dedicated 2Mbit international connection, I suggest you contact an ISP that offers this and agree upon a price (around $1000 per month for the bandwidth alone)



If you want some great connectivity to Taiwan - invest in those excellent undersea cables in the area. They have great reliability!

Exactly my point! ISPs don't allocate enough international bandwidth to their customers to be able to claim "As fast as line will go"..

willnz:  International traffic is around $500 per meg. If you want a dedicated 2Mbit international connection, I suggest you contact an ISP that offers this and agree upon a price (around $1000 per month for the bandwidth alone)


meg??

Do you mean $500 per megabyte? of traffic? Right....Or do you mean megabit of bandwidth?

Megabit.... the reason they don't allocate each customer 5Mbit of dedicated international bandwidth is because <b>most ADSL customers do not want to pay thousands of dollars per month.</b>

...International traffic limited to 256kbps...



When making blanket statements that Xtra ratelimit international connectivity to 256kbps, can you prove that they are doing that (rate limiting that is)? Or is it just that some connections are going slower than your max rate?

As posted earlier, slower international bandwidth is hardly an isolated issue to one ISP (in this case Xtra).

Obviously they can't allocate 5mbit per customer. I wouldn’t expect that; not for my $50/month.


The discussion was around streaming video from international sites. I’m merely pointing out that reason many users find streaming impossible is because their ISP doesn’t provide enough bandwidth to their particular pool of users. Which is why I feel that the whole “As fast as your line will go” slogan is a jip. And completely misleading.

Yeah, I see where you're coming from but really, international traffic is shared. The more people that use it, the slower it gets. If you feel that your ISP is sharing bandwidth between too many users, there are plenty of other ISPs to choose from. And there is plenty of information available here on GZ to determine which ISP is best for you.

yes, good speed for things such as streaming video is a big problem in New Zealand.  Any protocol that does not allow multiple connections will never fully utilise the potential speed of your connection.  I seriously believe this is a problem that needs to be fixed, but I see no resolution any time soon due to the complexity of the issue.  I have tried a number of legit pay stream services (mostly sport) and have never good as good connection as I believe should be possible.   The only time it has been acceptable (IMO) is TVNZ (inside NZ) and darkside P2P streams (where you have multiple users feeding you data).  I am not certain whether ISPs artificially limit the speed of a single 'connection', which would exacerbate this problem, but I have my suspicions this would be entirely possible.

For the record i'm on an Ihug 3.5MB plan.  This is not managed much from what i have noticed.  Video streaming has very rarely been able to maintain a decent stream at 50kB/s (out of a potential 300 or so)
