I'm asking because some people say that Zend Framework is not very effective when it comes to speed. Today I know the following frameworks: SpaghettiFramework, CodeIgniter, CakePHP and Zend, What is the best choice for creating a social network? Thanks.
This is very much a matter of opinion, but my vote goes to CodeIgniter. Very lightweight, very elegant, very fast.
Many of these 'frameworks' are heavy and bloated, and not really appropriate for high-performance situations. Some people like the 'swiss army knife' one-size-fits-all framework based approach, but this rarely results in the creation of an elegant and equally successful product.
