SSL inbound inspection delay

hey all, 

I've deployed SSL inbound inspection, connection gets really slow when SSL Inbound Inspection.
It takes almost one minute for the page to be loaded. Without SSL it takes 2 secs.

 

 Would any of you have a clue what could be causing the problem?

Found the problem. The page within customer environment has a zip file. So, when Palo Alto decrypts the traffic and sees that file. It decodes to check the packet and reencode it.  This is causing this delay. It stopped when I disable the Sec Profile from the rule.
