+# HF Jobs Utilities
+
+Utility scripts for testing and benchmarking Hugging Face Jobs environments. These scripts help you verify your Jobs setup and understand the performance characteristics of different GPU flavors.
+
+## Available Scripts
+
+### network-speed-test.py
+
+Test network download speed from within an HF Jobs environment. Useful for:
+- Verifying network connectivity
+- Comparing download speeds across different GPU flavors
+- Benchmarking before running large dataset downloads
+- Troubleshooting slow data loading issues
+
+**Features:**
+- Pure Python (no dependencies required)
+- Fast default test with small file
+- Optional `--large` flag for realistic ~100MB test
+- Clear metrics (MB/s and Mbps)
+- Works locally or on HF Jobs
+
+#### Usage
+
+**Run locally:**
+```bash
+# Quick test with small file
+uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py
+
+# More realistic test with ~100MB file
+uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large
+
+# Custom URL
+uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py \
+    --url https://example.com/testfile.bin
+```
+
+**Run on HF Jobs:**
+```bash
+# Test network speed on L4 GPU
+hfjobs run --flavor l4x1 \
+    -s HF_TOKEN \
+    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large
+
+# Compare across different flavors
+hfjobs run --flavor a10 \
+    -s HF_TOKEN \
+    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large
+
+hfjobs run --flavor h100 \
+    -s HF_TOKEN \
+    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large
+```
+
+#### Example Output

+
+## Why These Utilities?
+
+HF Jobs provides different GPU flavors with varying network configurations. These utilities help you:
+
+1. **Make informed decisions** - Compare network speeds before choosing a flavor
+2. **Debug issues** - Verify network connectivity when data loading is slow
+3. **Optimize workflows** - Understand if network speed is a bottleneck
+4. **Benchmark environments** - Document baseline performance for your use case
+
+## About UV Scripts
+
+This is part of the [uv-scripts](https://huggingface.co/uv-scripts) collection - ready-to-run Python scripts that work with a single `uv run` command. No setup, no virtual environments, just instant execution.
