There's meant to be a bunch of good things about it, testing your connection's maximum speed. More info here.

This is on Snap fiber 30/10 to Sydney

Here's LA.

Chicago

Any thoughts? Seems to register higher than speedtest.net

Thought I would see if there are any differences between Firefox and Chrome.

Interestingly my Upload is far better than my download. Maybe the Npref test server had it's download bandwidth (upload from my point of view) limited to 100mbit. Has anyone else managed to get over 100mbit on the upload?

Also the website shows an address that it thins I live at. Thankfully it is wrong, But it is still in Auckland.

When comparing speedtest methods you really need to understand how they work.

speedtest.net does some very interesting things with data which means it can under report connection speeds.

it can over report too. i used to get higher than sync speeds on adsl for download. (probably because of packet loss and suddenly lots of data in a row)

curiously i'm getting slightly slower upload speeds with it than speedtest.net. (10 megabit upload vdsl, the standard cap)

All "speedtest" sites are only as good as your understanding of them.

The weight and trust most people put in them is truly dismaying, as someone that does know how they work.

"The bitrate test relies on downloading binary files with multiple simultaneous connections in order to saturate your connection during a few seconds. We can then measure the bitrate accurately. The peak rate is corresponding to the average of 30% of the highest samples (50% when uploading). The average rate is calculated after having excluded 5% of the lowest and 5% of the highest samples. "

"By default, nPerf engine uses TCP mode which is more efficient because it uses sockets directly without going through the browser. To use TCP mode, you need to access remote services on TCP Port 8080 . If the TCP mode is not available (port 8080 is blocked), then test is done in HTTP mode. In this case the requests are going through the browser. This works well for bitrates up to 100 Mb/s , but beyond, this mode reaches its limits."

Now, if you people can interpret exactly what they mean by that, then by all means make comparisons between Speedtest.net results and nperf results.

Note that they haven't listed the size of the files, or the number of simultantous connections, so you can't account for TCP window size changes...

I should point out that most of the sites work ok, and give 'reasonable' results, most of the time... But strange or unexpected results are frequently not indicative of network issues, and the reported numbers are VERY FREQUENTLY not indicative of the performance you can expect in many real world uses.

Seems to work well for me. Their problem will be getting enough testing points around the world. Speedtest has reached a critical mass and is available everywhere.
