Chatbot Delay Issue BIG-IP ASM

Hi

 

I am facing delays of 15-20 sec in sending and recv of messages in my chatbot app which is part of a web app, the web app works fine but WAN users when use chatbot app, they face delays. I have tried to change my tcp profile to wan-optimized after going through an article regarding service delays for wan users but the issue still persist. I am using BIG-IP VM with ASM module.

 

Also please note that the app works fine when ASM is bypassed.

 

Regards

        Hi Lidev

         

        The on connect profile is used in case of multiple servers. I only have a single server for this application. I also have tried tcp wan optimized profile by disabling Nagle's algorithm as well. But still facing delays

      I have a single server serving this app and I have even tried tcp wan otpmized profile while disabling nagle's algorithm which might cause delays in normal communication. but still facing this issue.

        Hi,

        ​

        Normally either ASM transparent or blocking mode. F5 will inject javascript and addtional ASM cookie to tracking the web application.

        ​

        I had this experience issue because on the client side application cannot proceed too much http cookie and some of the request has failure.

        ​
