**💬 "hyperfine command"**

hyperfine is a **command benchmarking tool** that statistically benchmarks command execution speed. It includes warm-up, repetition, and static tests.

It supports automatic warm-up execution. After multiple repetitions, it outputs statistics (mean, standard deviation, min/max).

- **Concept**: It supports automatic warm-up execution.
- **Main feature**: After multiple repetitions, it outputs statistics (mean, standard deviation, min/max).
- **Advantage**: It supports both shell rendering and pipelines.
- **Usage**: It can export execution results to JSON.
## Installation and Download

hyperfine is installed via package manager or official script.

| Environment | Command |
| --- | --- |
| Ubuntu / Debian | sudo apt install hyperfine |
| macOS (brew) | brew install hyperfine |
| Rust cargo | cargo install hyperfine |
| Official binary | github.com/sharkdp/hyperfine/releases |
| Verification | hyperfine --version |

Installation is verified using `hyperfine --version`.

## Frequently Used Options

| Option | Description |
| --- | --- |
| hyperfine '<cmd>' | Basic benchmark |
| -w, --warmup <n> | Number of warm-up runs |
| -r, --runs <n> | Number of measurement runs |
| -p, --prepare <cmd> | Command to prepare before each measurement |
| --export-json <file> | Export results to JSON |

## 3 Essential Command Combinations

- `hyperfine 'grep pattern file' 'ripgrep pattern file'` — compare two tools
- `hyperfine -w 3 -r 10 '<cmd>'` — 3 warm-ups + 10 measurements
- `hyperfine --export-json result.json '<cmd>'` — save results in CI
**💬 "Show me an example of using hyperfine on a real server"**

I've organized common situations encountered on a real operational server in order.

### Step 1 · Verify Installation

Check if it is installed.

```
hyperfine --version || sudo apt install -y hyperfine
```

### Step 2 · Single Measurement

Measure command speed.

```
hyperfine --warmup 3 'grep -c ERROR /var/log/nginx/access.log'
```

### Step 3 · Comparative Measurement

Compare two tools.

```
hyperfine 'grep ...' 'rg ...'
```

## Actual Execution Screen

This is the result of measuring grep speed with hyperfine.

Real operational server

## In Practice, Here's How It's Used

### 1. Tool Speed Comparison

**Situation** — Compare grep and ripgrep.

```
hyperfine 'grep -c ERROR /var/log/nginx/access.log' 'rg -c ERROR /var/log/nginx/access.log'
```

**Result** — ripgrep is 6.42 times faster.

**Point** — It's a reliable comparison including standard deviation.

### 2. CI Performance Regression Detection

**Situation** — Track build time in CI.

```
hyperfine --export-json result.json 'make build'
```

**Result** — Results are saved to JSON.

**Point** — It detects regressions compared to previous commits.

## Actual Execution Screen

This is the result of comparing grep and ripgrep with hyperfine.

## Points to Note

- There may be interference from other processes during measurement. Measure on a dedicated server environment.
- Without warm-up, the cache effect of the first run is reflected in the results. A minimum of 1-3 warm-ups is recommended.
- Shell rendering includes shell overhead. For extremely short commands, run without shell using the -N option.
