Seeing similar behavior, especially with Google Docs, that we just posted about.
@Indu - So far I did not see this behavior on our end. There is a KB article in Netskope that has very good breakdown on how to approach troubleshooting performance related issues. This will be a good start, pick an application run some test as per this KB article to see where the latency is.

Also, ensure few basic things that if user is connected to nearest POP, Netskope client is updated to latest stable golden release or current version which will have fixes that might improve certain things. If you have remote access VPN's and on-prem firewall VPN's running in full tunnel mode then ensure Netskope traffic is configured in split tunnel mode to directly connect to web instead of going through VPN tunnel. There might be a chance the nearest POP might have some outages or issues which might had a temporary effect.
In case everything looking good and still not sure, open a support ticket and escalate it to your TAM to get better support.
Thanks
Also to add on to, ensure you are using DTLS tunnel for your client configurations.
Enabling DTLS option supersedes TLS (Transport Layer Security) tunnel for communication thereby improving the network process. TCP inherently slows the overall flow performance if the network has high latency and packet drops. To overcome this issue, use DTLS tunnel (UDP tunnel). To know the current protocol, click the Client icon > Configurations > Tunnel Protocol.
Thanks ark007 for your suggestions. We are already following setup as per KB. Using Digital Experience Management, we noticed that client to Netskope POP latency is ok, but Netskope POP to app latency is high. We are dealing this with Netskope support.
