We are implementing endpoint SWG using the Umbrella Module and Secure Client and we have noticed an increase in the time it takes to load a web page. This is especially true for sites with a lot of CDN content (advertisements, video, etc). Since the issue is not as apparent with SWG turned off, I do not believe this is occurring at the DNS layer, but I would like a way to prove that before making any assumptions. So far we have tried blocking Ads at the DNS and Web level with no luck. We tried turning Intelligent proxy on, which made it worse. We also tried disabling HTTPS inspection and adding specific sites to the selective decryption list with no luck. Has anyone been able to implement this successfully without impacting latency?
