Tuning PostgreSQL for a Matrix Synapse Homeserver

Introduction

Welcome to the guide on fine-tuning PostgreSQL for your Matrix Synapse Homeserver. Matrix Synapse is an open-source server implementation for the Matrix protocol, which powers an ever-growing network of secure, decentralised real-time communication. Ensuring that Synapse runs efficiently is crucial, and a significant part of that efficiency comes from the underlying database—PostgreSQL.

Out-of-the-box, PostgreSQL is configured with general-purpose settings that may not align with Synapse's specific demands. This guide will help you customise PostgreSQL, enhancing performance and ensuring your server can handle its unique workload with ease.

Remember, each Synapse server is as individual as its users, rooms, and usage patterns. Therefore, rather than prescribing one-size-fits-all solutions, I'll try to equip you with the knowledge to tailor your database settings to your server's distinct personality. Let's embark on this journey towards a more responsive and optimised Synapse experience.
