of a ``gearbox serve`` that somehow is wrapped as a service.

The best option depends on what you are familiar with and the requirements for

performance and stability. Also, keep in mind that Kallithea mainly is serving

dynamically generated pages from a relatively slow Python process. Kallithea is

also often used inside organizations with a limited amount of users and thus no

continuous hammering from the internet.

.. note::

   Kallithea, the libraries it uses, and Python itself do in several places use

   simple caching in memory. Caches and memory are not always released in a way

   that is suitable for long-running processes. They might appear to be leaking

   memory. The worker processes should thus regularly be restarted - for

   example after 1000 requests and/or one hour. This can usually be done by the

   web server or the tool used for running it as a system service.
