Resolve Performance Issues

Some internet connections are sensitive to upload bandwidth saturation. This sensitivity can negatively impact both upload and download speeds when an upload is in progress and cause potential dropouts. 

The following options are the most common ISPs that may produce this issue:

• ADSL (typically the most sensitive)
• Satellite connections
• Cable and fiber (typically less affected)

Adjust the Backblaze Speed Throttle

1. Open the Backblaze Backup Client for your specific operation system.
   • Preferences (Mac).
   • Control Panel (Windows).
2. Click Settings.
3. Select the Performance tab.
4. Clear the Automatic Threading/Throttle checkbox, and move the slider to change the throttle.

You may need to experiment with different values because some internet connections are more sensitive to upstream saturation than others.
