Kiri, a Rust container runtime, claims 80x faster startup than Docker Desktop; the figures depend on measurement

Kiri is a Rust-based container runtime aiming to replace Docker Desktop and OrbStack on desktops, and a viral clip claimed it starts containers 80 times faster using about 15 MB of memory. The author checked the claims against the project's README, benchmark files, and linked discussion threads without installing Kiri. The 80x figure comes from measuring Docker API calls, which ranges from 8x to 83x depending on what is timed, while a full CLI measurement shows roughly 17x. The benchmarks were run by the project's author on a single Apple Silicon Mac, and the memory footprint is reported as about 9.7 MB in the files versus the rounder 15 MB in the README. On Linux, Kiri runs without a virtual machine, which changes its isolation boundary compared with macOS.
