An interactive visualization of Jeff Dean's famous latency numbers every programmer should know, plotted over time. It also offers a terminal version accessible via cheat.sh/latencies.
Use cases
- look up typical latency numbers for disk, network, and memory operations
- teach systems performance concepts with a visual timeline
- check how SSD vs HDD vs RAM latencies have changed over the years
- quickly fetch latency figures from the terminal during system design interviews
- reference latency magnitudes when estimating system design tradeoffs
When to choose
- you need a quick, visual reference for latency magnitudes in system design
- you want an up-to-date version of Jeff Dean's latency numbers
- you prefer a terminal-friendly cheat sheet via curl
When to avoid
- you need precise, benchmarked latency figures for your specific hardware
- you need a tool rather than a reference chart
