+## Faster downloads
+
+You can test your download speed from Hugging Face's CDN at [fast.hf.co](https://fast.hf.co). This runs a quick bandwidth test against the nearest HF edge server, helping you understand your baseline throughput. You can also measure download speed from the terminal using the [`hf-speedtest`](https://github.com/julien-c/hf-speedtest) CLI extension:
+
+```bash
+hf extensions install julien-c/hf-speedtest
+hf speedtest
+```
+
+For faster transfers, the Hub uses the [Xet storage backend](https://huggingface.co/docs/hub/en/xet/index) with adaptive concurrency that automatically tunes parallel streams based on network conditions. See [Faster downloads for models](./models-downloading#faster-downloads) for details on tuning options like `HF_XET_HIGH_PERFORMANCE=1`.

 ## Using hf-mount
 
 For large datasets, you can mount a repo as a local filesystem with [hf-mount](https://github.com/huggingface/hf-mount) instead of downloading the full repo. Files are fetched lazily — only the bytes your code reads hit the network. Useful when your workflow expects local file paths (e.g. `tarfile`, `zipfile`, `imagefolder`) rather than Python iterators.

 ## Faster downloads
 
+### Test your download speed
+
+You can test your download speed from Hugging Face's CDN at [fast.hf.co](https://fast.hf.co). This runs a quick bandwidth test against the nearest HF edge server, helping you understand your baseline throughput before tuning any settings.
+
+You can also measure download speed directly from the terminal using the [`hf-speedtest`](https://github.com/julien-c/hf-speedtest) CLI extension:

+### Adaptive concurrency with hf_xet
+
 `hf_xet` is a Rust-based package leveraging the [Xet storage backend](https://huggingface.co/docs/hub/en/xet/index) to optimize file transfers with chunk-based deduplication. By default, `hf_xet` uses **adaptive concurrency** — it automatically tunes the number of parallel transfer streams based on real-time network conditions, starting conservatively (1 stream) and scaling up to 64 concurrent streams as bandwidth permits.
 
 For most machines — including data center environments — the default settings will already saturate the available network bandwidth. For advanced users on machines with high bandwidth **and at least 64 GB of RAM**, `HF_XET_HIGH_PERFORMANCE=1` raises concurrency bounds and significantly increases memory buffer sizes, which can help when downloading many large files in parallel.
