OK, so now we are all showing our age! And yes, the lexicon has become really muddied … generally the result of someone who doesn’t know (and thinking they do :-)), speaking the loudest and the longest and whaddaya know, all of a sudden we have “speed tests” and “capacity tests”, when really what is happening is that “data/information/communication rate” is being “measured/estimated”. Neither “speed” nor “capacity” is being “tested”. Oh, for the good ole days when … :-) _____ From: Starlink [mailto:starlink-bounces@lists.bufferbloat.net] On Behalf Of Ulrich Speidel via Starlink Sent: Wednesday, January 4, 2023 1:17 PM To: jf@jonathanfoulkes.com; rjmcmahon Cc: Dave Taht via Starlink; bloat Subject: Re: [Starlink] [Rpm] the grinch meets cloudflare's christmas present The use of the term "speed" in communications used to be restricted to the speed of light (or whatever propagation speed one happened to be dealing with. Everything else was a "rate". Maybe I'm old-fashioned but I think talking about "speed tests" muddies the waters rather a lot. -- **************************************************************** Dr. Ulrich Speidel Department of Computer Science Room 303S.594 Ph: (+64-9)-373-7599 ext. 85282 The University of Auckland u.speidel@auckland.ac.nz http://www.cs.auckland.ac.nz/~ulrich/ **************************************************************** _____ From: Starlink on behalf of rjmcmahon via Starlink Sent: Thursday, January 5, 2023 9:02 AM To: jf@jonathanfoulkes.com Cc: Cake List ; IETF IPPM WG ; libreqos ; Dave Taht via Starlink ; Rpm ; bloat Subject: Re: [Starlink] [Rpm] the grinch meets cloudflare's christmas present Curious to why people keep calling capacity tests speed tests? A semi at 55 mph isn't faster than a porsche at 141 mph because its load volume is larger.
