 <p>I've been running my homeserver on a cubietruck at home now for some time and am often replying to statements like &quot;you need loads of ram to join large rooms&quot; with &quot;it works fine for me&quot;. I thought it might be useful to curate a summary of the issues you're likely to run into to help as a scaling-down guide, maybe highlight these for development work or end up as documentation. It seems that once you get up to about 4x1.5GHz arm64 4GiB these issues are no longer a problem.</p>
