zsh-bench is a benchmarking tool that measures user-visible latency of interactive zsh, such as input lag and command lag. It also includes human-bench for studying human perception of latency and provides normalized results to judge what feels fast.

Use cases

• measure input lag of my interactive zsh setup
• benchmark zsh startup and command latency
• compare zsh plugin managers by performance
• test whether prompt latency is perceptible to humans
• optimize my zsh config for responsiveness
• evaluate powerlevel10k performance

When to choose

• you want objective, reproducible measurements of interactive zsh latency
• you are tuning or comparing zsh configs, plugins, or plugin managers
• you want latency thresholds grounded in human perception studies

When to avoid

• you need to benchmark non-interactive shell script execution speed
• you use a shell other than zsh
• you cannot run zsh >= 5.8 as your login shell
