Thought I would start a new post to get some comments about what appears to me to be bad performance. I am in the Khandallah area.

For sometime now i have been having gaming issues and am wondering if this is the problem.

As you can see below Australia seems great

Its just to the USA which of course affects gaming badly.

Maybe the USA tests are fine..not sure.

Often the issue is related to your TCP Window Size. Operating Systems tend to be customized for low latency local networks.

Where the Latency is high, it has an adverse effect on the performance of that TCP Stream.

It can be calculated by Window Size Devided by RTT (Round Trip Time) = Speed in mb/s

E.G A window Size of 1024K Divided by a RTT to Google of 311ms = 3.2mb/s

- Increase your window size

I consistently get 10mb/s to the U.S for downloads when I use multiple TCP Streams.

Hope this explains it a bit.

Thorndon here. Some sites simply don't load (sidestep.com & family), my flatties are having trouble too. Telstraclear's status page hasn't been updated since September so I wouldn't recommend that as a source of information about unplanned outages.

NZ sites load very well except those that are advertising supported. Speedtest reports all OK but then I expected it to.

Does TC use transparent proxies?

Here are my results testing on the same same servers as you (Two tests on LA and one on Sydney).







onecouch, sidestep.com loads. What DNS servers are you using? I updated to 203.97.78.43/44 from 203.96.152.4/12 which has problems with escapistmagazine.com

I've updated to the .43/44 set, and now everything I use is back to "normal" which is as good as can be expected with the rather undersized international links here

Are those low speed to the US normal????
They seem very low. Would be interested to see what ADSL get over the same routes.

As I said, if you use multiple sessions I'm quite positive that you will get 10 Meg.

Examples from my Download Manager - Downloading from the US:

Top Gear - 14x03 - Series 14, Episode 3 Completed
Stage Download
[Time-Taken]: 12 minutes 41 seconds
[Avg-Speed]: 989kB/s

Top Gear - 14x02 - Series 14, Episode 2 Completed
Stage Download
[Time-Taken]: 12 minutes 36 seconds
[Avg-Speed]: 990kB/s

2012 (2009) Completed
Stage Download
[Time-Taken]: 37 minutes 1 second
[Avg-Speed]: 1035kB/s

I get full speed as well with a download manager but most of the time I'm streaming data, gaming and using bandwidth that cannot use accelerators (ie multiple connections made to download a file in sections simultaneously).
