php - do i use ci_sessions to store session data -

Developing a site for a travel site, in the process when a user searches, I Manipulate it in session Submit what information is stored in the ci_session database by following this method I

  $ this-> session-> I am able to easily filter the data from userdata ();  

A general search in which the session data exceeds 20kb in 4 hotels; In the actual server environment, it is possible that the result is more than 200 hotels, i.e. 4000 KB data single users In each row, in the ci_session table.

This process is slowing down the application, what other way can I follow the search results to be very fast.

You can store session data in your database. CI sessions have the ability to handle it, there is no need to do it manually.

Read how to properly configure it may slow down if you need them on every site.
