I had a program called TCP Ping which was useful, will have to search my archive.

Does this only happen when downloading from this site? or does it happen with others too?

All large download files, be it from here or Microsoft or the download test files cloud based in England. Slightly different meter pattern during office hours, seems to vary from 11.6 to 16.4 mbits in equal measure. Ticket has been forwarded to Vivaciti NOC.

Well I have resumed testing with Jdast and extended the download test time to 15 seconds with multiple threads. So far the symptoms are the same, first 5 seconds full speed then starts reducing and getting a bit wobbly for the remaining 10 seconds giving an average download of 15 mbits. If I leave Jdast at its default settings of 5 second test I get 16.4 mbit average.

Have ticket open and waiting for NOC to get back to Vivaciti to try and explain.

Be interested in seeing how you fare with the new tester

Similar results.

The single thread tends to be all over the place but the x6 maxes out then starts to wobble and go downward. This seems to be irrespective of server as Jdast does multiple threads from multiple servers at once. First few seconds maxes out then starts wobbling about.

Another test for reference, similar graph both single and multiple thread with d/l stopping at one stage on single thread.

I've seen graphs like that when I forget test is running and refresh a web page

Mine just wobbles at the end:
