 ## Performance tips
 
-1. **Use gcloud for fastest downloads** - requires authentication but provides significant speed improvements
-2. **Download during off-peak hours** - typically late night or early morning
-3. **Use wired connections** - avoid Wi-Fi for large downloads when possible
-4. **Monitor disk space** - extracted archives can be 2-3x larger than compressed files
