I agree with this. All ORM solutions are notorious for adding performance
overhead. Their value is in extending the object-oriented paradigm to
database programming.
There's no substitute for writing SQL queries by hand, if performance is
your top priority. In fact, if performance is the only concern, you
shouldn't be using an RDBMS at all -- you should be managing data using a
custom storage module that you write, specialized to your application.
Also, you shouldn't be coding in PHP in the first place -- you should be
writing all your code by hand in assembler.
The point being that often a trade-off exists between development
convenience and runtime speed.
