Increase 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 memcached sessions.

To switch to database-based user sessions uncomment the following section in your :file:`/home/{user}/.rccontrol/{instance-id}/rhodecode.ini` file.

## 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 accoring to the type of database
beaker.session.sa.url = postgresql://postgres:secret@localhost/rhodecode
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.

## types are file, ext:memcached, ext:database, and memory (default).
#beaker.session.type = file
#beaker.session.data_dir = %(here)s/data/sessions/data

To switch to memcached-based user sessions uncomment the following section in your :file:`/home/{user}/.rccontrol/{instance-id}/rhodecode.ini` file.

## memcached sessions
beaker.session.type = ext:memcached
beaker.session.url = localhost:11211

and make sure you comment out the file based sessions.

## types are file, ext:memcached, ext:database, and memory (default).
#beaker.session.type = file
#beaker.session.data_dir = %(here)s/data/sessions/data
