The default options for the script do a separate TCP_MAERTS and = TCP_STREAM for 60 seconds while collecting ping latency. The output of = the script shows the down/upload speed as well as a summary of the ping = latency, including min, max, average, median, and 10th and 90th = percentiles.=20 The script makes it easier to optimize my settings because it makes the = latency figures more concrete. (I used to eyeball the ping output, = saying, "Hmmm. I think there were fewer outliers than before...") You can see the script on the "Quick Test for Bufferbloat" page on the = wiki at: = http://www.bufferbloat.net/projects/cerowrt/wiki/Quick_Test_for_Bufferbloa= t#Speedtestsh-shell-script Enjoy! Rich=
