This gives fascinating insights into the network topography of our visitors, and how much we might be impacted by high latency regions. Round-trip-time (RTT) is basically a measure of latency—how long did it take to get from one endpoint to another and back again? What is RTT? That’s exactly what this article is about.

Single-core memory bandwidth: Latency, Bandwidth, and Concurrency

John McCalpin

FEBRUARY 17, 2025

“Latency” is the duration from the execution of a load instruction (to an address that misses in all the caches), and the completion of that load instruction when the data is returned from memory. The example below is for a 2005-era processor with 60 ns memory latency and 6.4 cache lines -> 5.6 cache lines -> 5.6
