         <para>The Synapse reference server implemented in Python is known to be quite RAM hungry, especially when loading large rooms with thousands of members like #matrix:matrix.org. It is recommended to avoid joining such rooms if your FreedomBox device only has 1 GiB RAM or less. Rooms with up to a hundred members should be safe to join. The Matrix team is working on a new implementation of the Matrix server written in Go called Dendrite which might perform better in low-memory environments. </para>
         <para>Some large public rooms in the Matrix network are also available as IRC channels (e.g. #freedombox:matrix.org is also available as #freedombox on irc.debian.org). It is better to use IRC instead of Matrix for such large rooms. You can join the IRC channels using <ulink url="https://wiki.debian.org/FreedomBox/Manual/FreedomBox/Manual/Quassel#">Quassel</ulink>. </para>
