Benchmark Nvim

Neovim Startup Benchmark

Measure Neovim startup time and perform performance analysis.

Steps

1. Run benchmark with hyperfine

Execute the following command to measure startup time:

hyperfine --warmup 3 'nvim --headless +q'

2. Detailed analysis with startuptime

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

(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
