CI session database, lot of data

[eluser]broadband[/eluser]
Thank you for the reply and the solution. The problem was user_data datatype. When I changed

Code:

ALTER TABLE `ci_session` CHANGE `user_data` `user_data` LONGTEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL

everything worked fine.

And also yes I forgot to add $this->load->library('session'); in method test2()

Code:

public function test2()
  {
    $this->session->userdata('test');
  }

I just noticed when using database there is quite a performance hit.
