[The 7th Sage]

-My essential needs are minimum http requests, low page size.

-My second need is users should be able to create account on the website and be able to post articles, which will be published on approval of admin.

-Lastly a page which links all the articles, similar to http://www.wikihow.com/Category:Basic-Computer-Skills

I came across this page http://erickennedy.org/Drupal-7-Reasons-to-Switch and some other responses from Drupal users saying the new Drupal versions were extremely slow. I've never really used Drupal myself so you can tell me if this is true.
