Time-to-first-token (TTFT) measures how quickly an AI system generates output after receiving a request. In physical AI like warehouse robots or delivery drones, fast TTFT improves safety and productivity. Microsecond-level responses control basic motor functions, while sub-50-millisecond responses enable emergency obstacle avoidance.
A developer used a Teensy microcontroller with a light sensor to measure click-to-photon latency on Linux. Tests ran on desktop and laptop systems with Ada-generation RTX cards and Zen 4 CPUs using NixOS and Windows 11. The goal was to identify software queueing effects at 120 FPS on a 120 Hz display.
A mesh Wi-Fi system solves range issues but introduces latency and throughput taxes. Signal bars are a dangerous illusion; raw speed tests look fine, but ping spikes and packet drops ruin gaming and video calls. The author advises understanding network physics before buying a consumer mesh kit.
Latency is the delay for a single packet, measured in milliseconds. Throughput is the actual data transfer rate, always less than bandwidth. Bandwidth is the maximum link capacity, like a 100 Mbps connection. Low latency does not guarantee high throughput due to congestion and protocol overhead.
