I'll pull together a list of people to send the open letter to (trade = press, etc) Rich ----- Summary of note sent to these speed test vendors in early August = 2014 ----- Hi! I would love to see real-time latency measurements, and a summary of min = and max times in the final report. Your page currently displays a single = "latency" value, but it appears that it's simply the measurement before = you start the data transfers. It's really interesting to see that low = value, but also the range/max of the latency.=20 Why is latency interesting? I'm a member of the CeroWrt project that is = working to reduce latency in home routers (and everywhere else). Our = research has led to the development and testing of the fq_codel = algorithm that virtually eliminates bufferbloat (high latency during = heavy traffic). You can read about the project at: = http://www.bufferbloat.net/projects/cerowrt I'm asking you to consider implementing the web-equivalent of our "Quick = Test for = Bufferbloat"http://www.bufferbloat.net/projects/cerowrt/wiki/Quick_Test_fo= r_Bufferbloat By showing what happens to latency during transfers, = people can become aware of the problem, and that there's a fix for it. = (I'm using the CeroWrt firmware at my house. Ping times to Google only = go up by ~20-30 msec even when I max out the DSL link in both = directions.) --Apple-Mail=_B7677C9A-D7FF-47D5-804F-E84DF08DA3CF Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iQEcBAEBCgAGBQJUEjqkAAoJEH4agC/0z73/3FgH/2yJpmYJNnGZp7IvjJkrLAev HA+nrXRfE0eis22PKlKmyMXvTPbd15XsXBlrLXKNnfqKd57VUwiSsTdLIWFCFOTB gEVpy50dvbwvpJ9sum+07iX3SHlbJnb2TaGbNDqZzgqpwiryD9BPALTR23/jnEmQ Tj2nHNyzJuRCMO6VkHliWU6HjfXZ19dfTO+zlB4I+uDGS3mDKnyBES0N3wvRfbYx 4M1Om6GWSV+nIyC6RGyJkBItcIhTPE99MY417D4WqWAXjXJeotVcg1BRN7ylvbec /516CV6tsHPimXXsj+tvv58K/FZgxzLiQVaEs55HeVnd8wc0BHaWWXt7+FdSzSE= =iBjA -----END PGP SIGNATURE----- --Apple-Mail=_B7677C9A-D7FF-47D5-804F-E84DF08DA3CF--
