Performance

TIP

These are the legacy v4 docs. For other versions, use the links in the header dropdown.

zsh-abbr adds roughly 20ms + 1.6ms/abbreviation to first prompt lag, 24ms + 1.6ms/abbreviation to first command lag, and 20ms + 1.6ms/abbreviation to exit time.

Explanations of the measures are at https://github.com/romkatv/zsh-bench#what-it-measures.

Raw single-run data is available at https://oletsdev.notion.site/oletsdev/zsh-abbr-f2f3a1de08f14c8f8686ece171175400.

The performance suite uses zsh-bench. Run the performance suite with

zsh-bench --isolation docker --config-dir ./perf -- not-installed fresh-install zero-abbreviations ten-abbreviations one-hundred-abbreviations
