How “latency numbers everybody should know” decreased from 1990–2020
Not an intuitive thing but the data is fascinating. A couple of notes of people who are confused by it:<p>1) The &#x27;ns&#x27; next to the box is a graph legend not a data label (normally that would be in a box labeled legend to distinguish it from graph data)<p>2) The weird box and rectangle thing on the top is a slider, I didn&#x27;t notice that until I was looking at the code and said &quot;what slider?&quot;<p>3) The <i>only</i> changes from 2005 to present are storage and networking speeds.<p>What item #3 tells you is that any performance gains in the last decade and a half you&#x27;ve experienced have been driven by multi-core, not faster processors. And <i>that</i> means Amdahl&#x27;s Law is more important than Moore&#x27;s Law these days.
