It’s more likely that there’s something about your setup that is causing the performance issues, but without knowing more (for example: how large is “large”, and what are you running Roon on), there’s not much anyone can do to help.
If you want help, then In order for Roon’s @support team to better assist you, please post in the Support category of the forum and provide a brief description of your current setup and the nature of the issue using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so they have a clear understanding of how your devices are connected.
