 User Session Performance
 ------------------------
 
 The default file-based sessions are only suitable for smaller setups, or
 instances that doesn't have a lot of users or traffic.
 They are set as default option because it's setup-free solution.
 
 The most common issue of file based sessions are file limit errors which occur
 if there are lots of session files.
 
 Therefore, in a large scale deployment, to give better performance,
 scalability, and maintainability we recommend switching from file-based
 sessions to database-based user sessions or Redis based sessions.
 
 To switch to database-based user sessions uncomment the following section in
 your :file:`/home/{user}/.rccontrol/{instance-id}/rhodecode.ini` file.
 
 
 .. code-block:: ini
 
       ## db based session, fast, and allows easy management over logged in users
       beaker.session.type = ext:database
       beaker.session.table_name = db_session
 
       # use just one of the following according to the type of database
       beaker.session.sa.url = postgresql://postgres:secret@localhost/rhodecode
       # or
       beaker.session.sa.url = mysql://root:secret@127.0.0.1/rhodecode
 
       beaker.session.sa.pool_recycle = 3600
       beaker.session.sa.echo = false
 
 
 and make sure you comment out the file based sessions.
 
 .. code-block:: ini
 
       ## types are file, ext:memcached, ext:database, and memory (default).
       #beaker.session.type = file
       #beaker.session.data_dir = %(here)s/data/sessions/data
 
 
 The `table_name` will be automatically created on specified database if it isn't yet existing.
 Database specified in the `beaker.session.sa.url` can be the same that RhodeCode
 uses, or if required it can be a different one. We recommend to use the same database.
