Why isn't $this->session->set_userdata(‘item’, ‘value’) supposed to write the database ? It seems that you don't understand the idea behind the session class.[/quote]

Maybe this will convince you: example of CI session behavior from my other post

And this is just using one call $this->session->set_flashdata('item', 'value');

What if you add 10 session vars ? What if you store session data in an encrypted cookie on the client side ? How fast can you go ?

I don't store session data in the database so it isn't a problem for me. Besides, the performance increase when using a cookie with your modified session class will most likely be very small.
