I agree with jb the one thing it has going for it is a short name… It does only one thing but does that a) badly and b) arguably it only even does 1/2 thing as ingress and egress are simply not completely independent. Arguing that Ping (RTT) and jitter are “network engineer’s analysis and diagnostic” tools and hence out of scope for their simple tool shows that they are aiming to low (I would go as far as claiming that with the explaining text the aim is still on the “own foot” territory, but I digress).

I guess one thing that it does is shows anyone who is targeting netflix with 
slowdowns (or just not upgrading to meet capacity needs) where the problem is.

And since this is netflix, they really do only care about download speed :-(

they should care about download speed while also doing an upload, to prevent
