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

Usage

spd
spd --minimal   # script-friendly output
spd --json      # JSON output

Installation

From Crates.io

cargo install spd --locked

From Source

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.
