SQLite then it is possible to convert to MySQL or MariaDB using the steps provided
in :doc:`../configuration_database/db_conversion`.
In smaller installations you might not want to set up a separate cache. However
you can still tune your database. The following example is suited for a database
smaller than 1GB. MySQL will consume up to 1GB of RAM for caching. Please make
sure that your system has sufficient free RAM after the change, so that it does
not start to use your swap partition, when it receives a burst of requests. In
the given example your ``/etc/mysql/conf.d/mysql.cnf`` might contain the
following lines. (beware that this is the block for mysqld not mysql)
.. code:: ini

Tune PHP-FPM
------------
If you are using a default installation of php-fpm you might have noticed
If you are using a default installation of PHP-FPM you might have noticed
excessive load times on the web interface or even sync issues. This is due
to the fact that each simultaneous request of an element is handled by a
separate PHP-FPM process. So even on a small installation you should allow
more processes to run. For example on a machine with 4GB of RAM and 1GB of
MySQL cache following values in your ``www.conf`` file should work:
more processes to run in parallel to handle the requests.
.. code:: ini
pm = dynamic
pm.max_children = 120
pm.start_servers = 12
pm.min_spare_servers = 6
pm.max_spare_servers = 18
Depending on your current PHP version you should find this file e.g. under ``/etc/php/7.4/fpm/pool.d/www.conf``
