Yes, I meant the Flash client. Nice work.
I look forward to seeing future versions.

Thanks for the quick reply. Just to clarify and make sure we're on
the same page, this is about the Flash client, not the Java client.
anything, just a reference implementation of a wrapper around the
Flash client. The idea, I believe, is to give a working example of
how one could go about doing it, and how the interface can be
relatively nice looking, with the hope that more people would
integrate into their sites. That said, I imagine many may use the
reference implementation as a base on which to build something a
little more feature and information complete.
I'm not aware that the Flash client currently makes all of the data
couldn't. As far as I can tell, the Flash client itself only renders
the detailed data in a somewhat cryptic command-line-like fashion that
only someone quite technical would be able to parse. I would image it
could be quite easy to make that same information in it's current

Defaulting to only copying the list, and top posting (based on this

I just ran the client on my home Linux workstation. Nice job, I'm pleased
that NDT based on-demand testing will continue even if the face of growing
Java JRE limitations.
While the client gave me the upload/download and RTT data, there was no way
to dig into the test results to figure out if these numbers were good, bad,
As the original developer of the NDT code I will repeat my mantra, the
server is collecting data that can be used to interpret the test results. I
agree that the majority of NDT users are not interested in knowing more than
the basic data, but I still think that M-Lab should strive to educate them
on the value of knowing more.
For example, the NDT server calculates how the clients selection of TCP
window size impacts the upload and download speeds. These are the upper
bounds of what could be achieved over the connection. The server also
calculates the speed based on the Mathis formula, this is also a bounding
I think it would be great if the display somehow showed the user where they
fit in relation to these limits.
At a minimum, I would also like to see a button on the screen that would
send me the test details. Again, I know that few, if any, users
want/need/understand this data, but the point is, they could look at it or
send it to the IT staff when reporting a problem.
