Issue/Introduction

Is PacketShaper throttling/restricting a connection?

Resolution

To find out whether  the PacketShaper is responsible for the lack of performance, you can measure the bandwidth used by creating a separate class for this connection. The class will specify the IP address of the server/website. If you don't know the IP address of the server you are querying, you will need to do an ns lookup to find the address.

1. Create a child class of Inbound/Localhost. Specify the following attributes:
   Service: IP
   Protocol Family: IP
   Outside IP Address: specify IP address of the server/website
2. Enable Traffic Discovery within Class.
3. Go to the Monitor tab in the Legacy/Advanced UI.
4. Generate the traffic in question or retry the operation (e.g., download a file, reload website, etc.).
5. On the Monitor tab, watch how much bandwidth the operation is using and observe if the bottleneck is being created by PacketShaper or by an external influence such as website load.

Using this method you also may be able to determine how much bandwidth to specify for a particular partition.
