What are Priorities?

Priorities allow users to prioritize internet/network traffic of one filter (application) over others. NetLimiter's internal priority engine automatically detects when application (or custom filter) transmit data to/from internet and then starts to restrict other applications/filters in order to allocate enough bandwidth for apps with higher priority.

NOTE: Applications with highest active priority always take as much bandwidth as they need. Rest of the bandwidth is shared among the rest depending on their priority.

Priority levels

Critical: Designed for situations where quick response is crucial for good performance. Suitable for VoIP applications and online multiplayer games.

High: Ideal for interactive applications like web browsers when some other applications uses internet in the background.

Normal: If you don't set a priority for any app, it will have Normal priority by default.

Low: When app has a Low priority it will be restricted if any app with Normal or higher priority will be active (transferring data). Useful for various non-interactive background services.

Priorities vs. Limits

Main differences between Priorities and Limits:

  • Priorities are fully automatic. Just select an app with high priority and let NetLimiter 4 work.
  • Limits are more rigorous and exact. If you want to give any app specific constant size of bandwidth then Limits are way to go.
  • To share your bandwidth among apps with Limits you need to know maximum/total bandwidth size of your current internet connection.
  • Priorities detect total bandwidth size of your current internet connection dynamically (on the fly). This is handy if you often change your internet connection (you move among several Wi-fi networks and providers). This dynamic detection is not 100% acccurate, nevertheless very reliable.

Fine-tuning settings

You can adjust behaviour of priority engine using settings located on Priorities tab in the main screen.
