Speedtest shows loaded latency information now too. Agreed, sometimes latency is more important than max bandwidth

- meinheld111 3y ago> sometimes latency is more important than max bandwidth we probably could have stuck with sneakernet if it wasn‘t more important most of the time
- BrianHutch 3y ago"never underestimate the bandwidth of a station wagon full of tapes" as the old saying goes.
- shagie 3y agoConsider the data connections from Arecibo or Ice Cube (which has many of the same problems). From Wikipedia: > Observational data were recorded on 2-terabyte SATA hard disk drives fed from the Arecibo Telescope in Puerto Rico, each holding about 2.5 days of observations, which were then sent to Berkeley. Arecibo does not have a broadband Internet connection, so data must go by postal mail to Berkeley. https://setiathome.ssl.berkeley.edu/~korpela/papers/CISE.pdf https://setiathome.ssl.berkeley.edu/~korpela/papers/CISE.pdf > This 2.5-MHz band is recorded continuously onto 35 Gbyte DLT tapes using 2-bit complex samples. Each tape holds about 15.5 hours of data. The entire sky survey is expected to require 1,100 tapes, for a total of 39 Tbytes of data. > The recorded tapes are shipped to Berkeley, where we subdivide them into small work units on four splitter workstations. ... --- https://icecube.wisc.edu/about-us/facts/ https://icecube.wisc.edu/about-us/facts/ > One terabyte of unfiltered data is collected daily and about 100 gigabytes are sent over satellite for analysis. It's better now (the South Pole does have a broadband link)... but Ice Cube is only sending 10% of its data.
