[IMPORTANT, please fill the questions]
Application name and version: Wordpress Version 4.4.2
Is it an installer, cloud image or virtual machine?: EC2
Operative system/Platform (Linux, Windows, OSX)(x86/x64): Linux
Was it installed as the root user? Not sure. I used the EC2 in AWS marketplace.
Is there anything you've done and/or tried with the application before posting here?
I used this tutorial to use Amaon RDS instead of internal DB: https://wiki.bitnami.com/Amazon_cloud/Migrate_Your_Application_Database_to_Amazon_RDS
After few weeks, WP either is not responding at all, or with huge latency.
