  1. …indicates the original set of numbers were more like 10us, 250us, and 30ms. And it links to https://github.com/colin-scott/interactive_latencies which seems like it extrapolates progress from 14 years ago: // NIC bandwidth doubles every 2…

  3. It is indeed a year. The latencies are based on the calculations done by Colin Scott in https://github.com/colin-scott/interactive_latencies and support projecting out into the future. Sorry it's not as obvious as it could be.
  4. …numbers from back then to _guess_ what future numbers would look like! (I was fooled by it too) See https://github.com/colin-scott/interactive_latencies/issues/...
  5. …this tool makes inaccurate projections from 2012 data. It is not at all accurate for 2020. See: https://github.com/colin-scott/interactive_latencies/issues/...
  6. It looks like that because an inaccurate projection from 2012 has been made by the tool. See https://github.com/colin-scott/interactive_latencies/issues/... .
  7. Yes, this is a huge problem with the data for 2012 onwards. See: https://github.com/colin-scott/interactive_latencies/issues/... .
  8. I was curious too, the network one is a TODO: https://github.com/colin-scott/interactive_latencies/blob/ma... Although I'd expect more jumps than Fast Ethernet to Gigabit, it's true the consumer space is kind of stuck on Gigabit (with 2.5…
  9. …a nanosecond or so, which leaves almost all of the latency budget for existential latency. edit: https://github.com/colin-scott/interactive_latencies/blob/ma... The data on this page is simply extrapolated using formulas and guesses.
  10. …of the blocks so it's more useful going forward) Fwiw the "fork me on github" banner points to: https://github.com/colin-scott/interactive_latencies
