1.Our SWG customer said that their students indicated the internet speed was slow.

2.We by pass all the network applicances one by one,and we found the SWG is the major issue.

3.We also found the application control is the cause of this problem.

We have the 100 mb leased-line.

(1) If we by pass the SWG,we got the download speed is about 92.92 Mbps and the upload speed is about 90.03 Mbps.

(2) If we enable the SWG service,we got the download speed is about 13.08 Mbps and the upload speed is about 50.20 Mbps.

(3) If we enable the SWG service (but disable the application contro ),we got the download speed is about 61 Mbps and the upload speed is about 90 Mbps.

4.We only block the P2P application in the application control.

 Why the application control causes such a big impact?

 Any solution can solve it?

5.The SWG is version 5.1.0.39

What mode is the SWG operating in?

Where is it located on your network?

Have the net internal subnets been defined in the networking configuration?
