Incredibly slow TTFB on brand new install - AKS, docker

Your software
My Mautic version is: 5.0.4
My PHP version is: 8.1
My Database type and version is: mysql 8

My problem is:
have been using mautic for years but moving to Kubernetes set up, clean install, not a migration. I have migrated several of our appliations over, using an application gateway and also tried the nginx-ingress (thought that was the problem for a while) but no avail.

I have checked all php packages, I’ve moved the cache, and logs off of the permament storage, i have redis and opache optimised, and checked, i’ve been through every possible nginx setting multiple times, checked disk speed mysql speed and everything else several times, and files load insanely quick, there is just a massive delay of between 30s and 70s from the initial request and TTFB, everything else is like lightning. I’ve installed three times. Tried moving the ssl to to ingress. And the same php/nginx docker is running other php applications with great speed. I’m completely at a loss now, any help or support is welcome! Happy to share my experience where i can!

Thanks all!
Steve
