Well, our concern with the browser based tests was that - as of 4 years ago - your typical browser and pc could not drive the network to saturation at speeds much greater than 20Mbit reliably. Neither could netalyzer. Thus, netperf-wrapper - now good to 40Gbit - was born. So some work on determing the real cpu usage and network capability of the client machine for these tests would be nice. I certainly do see bloat on the comcast 110 and 200Mbit services almost as severe as the lower end services using the netperf-wrapper tests. > > On Fri, Apr 24, 2015 at 4:04 AM, Mikael Abrahamsson > wrote: >> >> On Thu, 23 Apr 2015, Dave Taht wrote: >> >>> justin: >>> >>> thx for nuking the log scale. that makes the bloat much more visible >>> here (typical cablemodem) >>> >>> http://www.dslreports.com/speedtest/322800 >>> >>> I am puzzled as to my post fq_codel result here at T+40 and will have >>> to repeat... >>> >>> http://www.dslreports.com/speedtest/322992 >> >> >> This is my DOCSIS3 250/50 connection: >> >> http://www.dslreports.com/speedtest/349547 >> >> During the evenings (as it was when I tested now) I seem to not get over >> 100-150 megabit/s downstream, indicating it's saturating on the coax seg= ment >> at peak usage.
