Things I noticed: * clear division between technologies in bandwidth * the log scales are a great way to visualize things * you can make out the different bandwidth "tiers" that cable providers offer * fiber doesn't seem to show such tiers as much * DSL really drops off around 12mbit as expected, but there are some well above that. User error when running the test? I really like best/worst lists at the bottom. How could this graph/data be used to measure progress on the bufferbloat front? It would be neat to have an animation over time and hopefully watch the points drift to the left. What if the graph had the ability to toggle data sets on/off: * by technology * by ISP * by region Thanks for pointing it out -- Matt Taggart matt@lackof.org
