zsh-bench

Measures latencies like input lag and command lag that directly impact user experience, as the README emphasizes 'user-visible latency' over synthetic benchmarks.

Includes human-bench to test human sensitivity to latencies, helping determine what feels instantaneous, based on the 'How fast is fast' section with blind studies.

Benchmarks predefined Zsh configs, plugin managers, and custom setups with detailed results, as shown in extensive tables comparing performance across frameworks.

Supports Docker and user isolation for consistent testing across environments, ensuring reliable comparisons, as described in the usage options.
