Almost true

I agree with Rasmus and have note used application frameworks for those reasons. However just a month ago I discovered the Laravel framework and am pretty impressed with it-deadly simple, solid, éloquent code.

I don't know Laravel extensively but from what I could gather, it suffers from most of these problems. Making it simple, should not mean make it inefficient.

Well, I don't know... Till now I guarded myself from using PHP frameworks because of the "all you don't need" inside, many of them are pretty much stuffed with lot of things I will never use and also found that often they are over-complicated. So I used my own kind of framework structure to put simple things working simply (and I refer from time to time to PHPClasses :) )
As for the Laravel, I'm not high-end PHP specialist, but it seems to me that it is for PHP development what Jquery came to be for Javascript. And I like that. So I give it a try. Note that the creator of Laravel used to be a .net developper and he acquainted with php since its 5.3 version, which is intriguing enough for me.

Otherwhise, as Rasmus said, if have to use a pre-made - Wordpress or Drupal (I and find also that Drupal is too much complicated, at least till version 7)

What Rasmus meant is that Wordpress and Drupal are optimized for blogs or content publishing. So, supposedly the inefficiencies should be less if you use them just for those purposes.
