The client (or pcap) has a threshold of around 50Mbit or some systems (lower specs) where if you cross that threshold, it can’t keep up with all the traffic.
It works well on my main Windows desktop though; accounts for every GB I download/upload. The above screen shot was actual internet traffic as well, not LAN traffic. But yeah, sounds like libpcap is not reporting correctly in Ubuntu. :-/
So I kept an eye on the Network tab while downloading some files. Firefox was downloading a 506 MB file and it’s download manager said A.BC MB/s, but at the same time, Whatpulse’s network tab was saying A.BC Mbit/s. It registered 63 MB downloaded (which x8 is just under 506 MB) …
I’ve tried multiple previous versions, including betas, and none of them seems to want to work.
