3.To modify the maximum queue size allowed in the queue, double-click Queue Size and enter new values. The minimum number of queue requests is 10. The maximum number you set depends on the file descriptor limit of your system, but it cannot exceed 2,400. Each request in the queue takes up one file descriptor. To save the new parameters press [Enter].

Increasing these values can greatly affect the performance of WebQoS.

4.If you selected the Weighted Fairshare policy, you can modify the Weight.

The maximum weight is 100. The default values are: High 6, Medium 3, Low 1. To save the new parameters press [Enter].

5.When you have completed your changes choose [OK].
