APM Portal Access slow on Port 443

hi Everyone,

 

I am facing a slowness issue with my Portal Access configuration, when i access them via APM it is very slow, but when i bypass it is fast. I tried using http watch and found that some of the pages are getting response of 404. But that is not the case when i am bypassing the APM.

 

I assume that the Rewrite profile is taking a long time to rewrite the content. Is there any way i can troubleshoot the issue.

 

I have one Virtual Server with 8 portal access configured on it. some of the applications which are running on port 80 in the back end is working fine. while the portal running on port 443 shows a huge delay.

 

Vs 443 offloading --> Portal Access 80 good performance.

 

Vs 443 offloading --> Portal Access 443 too slow.

 

BIG-IP version 11.6.0 HF4

 

Thanks.
