mercutio: i think that's his hard-disk being slow, it got all the data, then it had to write it to disk...

I doubt it. The disk system on both systems I used is the same.

Zeon: Not too surprising considering TCL peering policy.

Are you suggesting that TCL is favouring the speedtest servers but managing other hand over?

No, what he means is TelstraClear don't peer (APE/WIX/CHIX). They charge big bucks if you want to connect with them and deliver content to their customers.

Nonetheless, Snap should have sufficient capacity to TCL.

speedtest.net is hugely unreliable.

The speed test I posted proves that Snap does have sufficient capacity to TCL.

The test to the US I provided proves that access to the content being tested is managed differently to the US than to TCL customers.

As TCL is Snaps upstream, APE/WIX/CHIX peering is having no impact at all to the testing.

By a factor of 40 times?

huh, speedtest.net says 75 megabit, which is about 9 megabytes/sec, and you got 10mb/sec with that http test and 8 megabytes when writing to disk is involved too. at least that's why i think it'd show 2 megabyte/sec diff.

2012-09-19 15:16:27 (2.17 MB/s) - `testfile-100mb' saved [104857600/104857600]

The Speed test showed 9Mbytes/s, the wget showed 2Mbytes per second.

That's a factor of 4 times, yes, sorry, not 40. Mixed up my bites and bytes.

2012-09-19 03:33:12 (8.29 MB/s) - `testfile-100mb' saved [104857600/104857600]

US pull of the same file showed 8.29 mbytes on the same file.

What am I missing?

~# time cp testfile-100mb t2/testfile-100mb

real 0m0.302s
user 0m0.000s
sys 0m0.216s

Given the write time to write a file on that disk system, I really doubt that the disk is a factor.

Again what am I missing?

the 10mb sec that it showed on the fast test?

you're going to get faster on a dedicated server than a telstraclear cable connection. you already know that 100 megabit telstraclear cable isn't great. now we just need to see how snap ufb compares :)

Snap's speedtest.net server is in Christchurch.
fry.snap.net.nz is in Auckland.
Snap peers with TCL in both locations, so routing and performance might differ.

I reckon the HTTP download test is more accurate than speedtest.net, since your computer doesn't have to worry about Flash getting in the way.

DonGould, where are you? Can you do a traceroute to speed.snap.net.nz and fry.snap.net.nz from your cable?

Can I ask what was the point of doing a national test when the issue is with International speeds?

Go hard, that's the next stage. Just worried about proving the last mile beyond reasonable doubt for now.

The reason for that is it's been mentioned there are speed problems even nationally. So let's cut our problem in half - and sort that first - since it's a prerequisite for good International performance.
