# SpeedOf.Me - LLM Information

> SpeedOf.Me is a browser-based internet speed test that works on all devices without plugins.

## About

SpeedOf.Me is a broadband speed test launched in December 2011. It measures download speed, upload speed, and latency using pure JavaScript - no Flash, Java, or browser plugins required.

## Key Features

- Works on all devices: desktop, mobile, tablet, smart TV, game console, in-car systems
- Pure JavaScript - no plugins or installation required
- Single-stream testing for real-world accuracy
- Real-time bandwidth graph visualization
- Test history with CSV export
- Supports gigabit connections (up to 10 Gbps)

## How It Works

1. The test downloads sample files from the nearest CDN edge server
2. Measures actual throughput over multiple passes with increasing file sizes
3. Uses single-stream sequential downloads (not parallel) for realistic results
4. Upload test uses similar methodology with POST requests
5. Latency measured via small probe requests
