Run benchmark with hyperfine Execute the following command to measure startup time: ```bash hyperfine --warmup 3 'nvim --headless +q' ``` ### 2. Detailed analysis with startuptime ```bash nvim --startuptime /tmp/nvim-startup.log --headless +q ``` Read `/tmp/nvim-startup.log` and analyze: - **Total startup time**: Time shown in the last line of the log - **Slowest plugins TOP 5**: Items taking the most time in sourcing - **Phase breakdown**: - reading vimrc (init.lua) - loading plugins - syntax/filetype - other ### 3. Output format Report results in the following format: ``` ## Benchmark Results ### hyperfine Results (Include hyperfine output as-is) ### Slowest Plugins TOP 5 | Rank | Plugin | Time (ms) | |------|--------|-----------| | 1 | xxx | X.XX | | ... | ... | ... | ### Phase Breakdown - init.lua loading: X.XX ms - Plugin loading: X.XX ms - Other: X.XX ms ### Optimization Suggestions (Provide suggestions based on slow plugins if applicable) ``` ## Notes - `--warmup 3` in hyperfine warms up the cache - Consider lazy.nvim lazy-loading settings in analysis --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/koki-develop) — claim your Tome and manage your conversions.
