Prestashop 1.7.4 Speed/ Loading issue on Apache2, EC2 PHP-FPM Opcache

[bhavinrana07]

Dear Prestashop Gurus, 

I have recently moved my Prestashop 1.7.4 site to AWS Infra, ec2 with and PHP-FPM 7.2 on Apache with Opcache. 

it seems the site is not loading as previously. I am sharing the Debug Profile report. 

• in the PrestaShop Cache it shows - Mb (nothing) does it mean that the server is not using the cache ?
• also on the middle bottom it shows nothing for the Hooks/Module , Time, Memory usage, do you know why?
• does this mean the cache is not working ? what can be the reason?

• Strange thing is that the RDS and EC2 CPU never goes more than 15 %, not able to use the AWS resource fully. what can be the reason for that ?

Edit:

added PHP INFO Variables

Thank you so much  and have a great day ahead!

Best,
