Running wordpress in eks pod without volumes (all, mysql and files in pod filesystem for testing purposes) gets 1.5s average response time for curl http://localhost, but if I run same configuration in a minikube cluster it takes only 0.5s, same database and php content (restored from backup).
Where I should look to start?
I'm using this docker image https://hub.docker.com/layers/wordpress/library/wordpress/php7.4-apache/images/sha256-483ce1761cdf5580e0259f68498d6e5e331dd6038fe339c9538420a26f21275f?context=explore
Nodes have 16Gb RAM and 4 vCPU (wordpress is pink graph)
Volume instance monitoring:
Xhprof results:
Update:
I have create an isolated ec2 instance with same eks node AMI and I get the same results.
