I don't know that I would want to run a production site with Magento and
Drupal with less than 4gb of ram. The cores = more visitors concurrently
to your website. Unless very well designed, mysql/mariadb threads will
only use a single core per query, so one user on the site could
potentially stall the site with a huge query. Having multiple cores
means multiple queries.
Naturally it is more complicated than that, but I figure with the
generalities you are asking about, that about fits the bill.
