PAC file users facing Slowness issue

Dear Team,

One of my client facing internet slowness issue with PAC file. I did the troubleshoot and found strange issue. There is no issue on throughput and downloading. They are facing slowness while surfing.

Kindly Note:- The client has no local breakout environment.

In the pcap, we are able to see that traffics first hits on client DNS, then after it is taking zscaler path which is not acceptable.

as far as we know that all traffics should be manage by Zscaler in the Tunnel 2.0

what is suggestion and solution for this scenario?

Hi Malik,
What do you mean by “In the pcap, we are able to see that traffics first hits on client DNS, then after it is taking zscaler path which is not acceptable.” You can exclude the DNS from the Zscaler tunnel and send it direct by adding *:53 to the Destination Exclusions in the App Profile.

i made the changes but unfortunately issue remains the same.
