What are the meanings of all the terms in this slide? Why is the correct operator to roughly compute (guesstimate) the improvement in performance multiplictive and not instead bottle necked by the new weakest link?

  • \$\begingroup\$ I think the answers you're looking for are in this article. In particular, it points out that the "10x faster" is "CEO math," and that real-world workloads will see less improvement. \$\endgroup\$ – DMGregory Nov 23 '15 at 12:26
  • \$\begingroup\$ @DMGregory But why is it supposedly multiplicative i.e (a * b) vs. min(a, b)? \$\endgroup\$ – wolfdawn Nov 24 '15 at 15:49
  • \$\begingroup\$ Because it's hand-wavy "CEO math" and isn't a real measure of performance. I wouldn't try to read that slide as a literal claim of multiplicative performance scaling. \$\endgroup\$ – DMGregory Nov 24 '15 at 18:00
  • \$\begingroup\$ @DMGregory Makes sense. Would be strange if there was a huge boost. \$\endgroup\$ – wolfdawn Nov 25 '15 at 14:46
