It looks like we've had ADSL 2 enabled here. My router is showing the following.

Data Rate
Stream Type	Actual Data Rate
Up Stream	963 (Kbps.)
Down Stream	17849 (Kbps.

This looks really impressive, but with my current ISP my international downloads are reporting on average about 2 MBPS and uploads are at about 256 KBPS. This is with a max/max plan.

With the connection appearing so impressive, should I expect more, and am i likely to get faster speeds if I change to another ISP?

I guess what I'm asking is if I'm being constrained by my ISP's bandwidth given that the connection looks so good.

Thanks and merry Christmas all.

This seems to be the speed from the modem to the Exchange... And what about from there?

And then reality settles in... How can people take advantage of such faster speeds, if the ISPs underinvested in infrastructure and bandwidth availability?

Right. I realise I'm not going to get anywhere close to those speeds, but there seems like a huge deficit here and that's why I wonder if I change ISPs, whether I'll be better off.

I am with Orcon at the moment, so I was interested in the updated stats published yesterday about performance, since I sure don't seem to be enjoying anything flash.

I have a FS/FS (Flood) plan with Xnet and just got the following Speedtest.net result to their server in Los Angeles:

Oh -- silly me -- I just realised that you probably can't read those numbers. Here they are in text, just in case:

DOWNLOAD 4576kbps UPLOAD 491kbps PING 171ms

On this score, your Orcon FS/FS connection is definitely under-performing

Where abouts are you jmosen? If you're a fair distance away from the actual exchange building, your DSL signal may be coming from a cabinet in between you and the exchange -- a lot of cabinets still only have 2Mbit backhaul, so even if the cabinet is right outside your front door, regardless of what you connect to it at it's not going to go any faster :(

I'm in Linwood Christchurch.

Actually one interesting thing is that last week, I downloaded the office 2007 SP1. I presume this is being cached locally somewhere, but i was getting over 10 MBPS on this download. this suggests to me that I'm capable of getting much better speeds than I am getting, and I'm being short changed on bandwidth.

Hmmm that rules out being on a cabinet then - what speed to you get doing a speedtest on www.nzdsl.co.nz ?

I know Orcon's some minor international bandwidth issues lately, but I use them myself and only noticed a very slight decrease in international speeds for that time

Can't tell you sadly. that site is useless to me. I'm totally blind and they use lots of Flash that doesn't have text labels for the buttons, so I can't even initiate the test there.

Give this one a go:

http://www.nzdsl.co.nz/meter/initialmeter.php

Not quite as accurate but it should give a fair idea. If you're still not able to get the results, PM me your Orcon username and I'll get someone to check what speed the test came back at (nzdsl is run by Orcon's system administrator)

Wow!
8.04 Mbps

which means you can download at 1029.15 KB/sec. from our servers.

OK so this would be consistent with the kind of download I was getting with the Office Service Pack. And it would suggest that international bandwidth with Orcon here is pretty bad.
