# spd • CLI Speed Test

spd is a speedy zero-copy Rust CLI that uses Cloudflare's global network to accurately measure 10Gbps+ internet speeds with minimal memory footprint.

## Example Output

![Example Output Image](./output.png)

## Usage

```bash

spd

spd --minimal   # script-friendly output

spd --json      # JSON output

```

## Installation

### From Crates.io

```bash

cargo install spd --locked

```

### From Source

```bash

git clone https://github.com/0mykull/spd.git

cd spd

./install.sh

```

## How It Works

- spd targets Cloudflare's edge using 8 concurrent streams for 10 seconds (plus 1s warmup) to saturate modern connections.

- Latency: Measures HTTP RTT to 1.1.1.1.

- Download: Streams 64KB chunks using zero-copy processing to minimize heap allocations.

- Upload: Pushes a shared 1MB payload (Arc) via HTTP POST to eliminate memory overhead.
