[STR .]

Adrian,

That was my plan after I have enough samples with just 1 probe.
I will keep you posted.

Thanks!

The only benefit speedtest has over other testing solutions (iperf, ftp) is the existence of a ton of test servers. This means you can measure (with best effort) available bandwidth between two points on the internet (not your own network).

@STR: you can set up multiple probes and assign each one a different offset so that you'll be sure the speedtest don't overlap and you don't get slowed down by your uplink. Or specify the offset as part of the host configuration (should work)
