db0<p>An observation I've made when asking for volunteers fit improving our <a href="https://hachyderm.io/tags/lemmy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>lemmy</span></a> instance. There's a lot of <a href="https://hachyderm.io/tags/sysadmins" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sysadmins</span></a>, a few backend developers and practically no frontend developers. For some reason it seems sysadmins tend to be the mostly common early adopters. Sadly that also means we don't find anyone to onboard the cool features I've developed, on the UI</p>

I checked the RAM usage in my admin and it's consistently above 90%. I have 1GB ram and figured I wouldn't need more since I don't get much traffic, but now everytime I try to open my site it takes forever to load.</p><p>What I don't understand is that, on the Oracle VPS, I not only had my Go site, but also had Caddy, Plausible for analytics with a <a href="https://hachyderm.io/tags/postgres" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>postgres</span></a> DB and never had any issues. Now, all I have is the ghost site, mariadb, and caddy and nothing works.</p><p>Do I need more RAM or is this a DO thing? Both the Oracle and DO VPSes are hosted in the EU which is pretty far from here, to be fair. I do suspect it's a RAM issue because I can't even ssh into the VPS. When I try to open my site, the connection just loads until it eventually times out.</p><p><a href="https://hachyderm.io/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linux</span></a> <a href="https://hachyderm.io/tags/go" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>go</span></a> <a href="https://hachyderm.io/tags/GhostCMS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GhostCMS</span></a> <a href="https://hachyderm.io/tags/nodejs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>nodejs</span></a></p><p>EDIT: adding the link in case someone wants to check it out, could just be my distance from the server </p><p><a href="https://tawandamunongo.dev" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">tawandamunongo.dev</span><span class="invisible"></span></a></p>
