GhostPubCalc Partner Disclosure (Ghost v5 Publisher Dossiers): Outbound /go/ hosting referrals may earn GhostPubCalc a partner commission at zero extra cost to you (Read full disclosure).
GhostPubCalc compiles six production infrastructure dossiers covering Ghost v5 Node.js 20 and MySQL 8 memory ceilings, Amazon SES versus Mailgun bulk relays, zero-churn Substack Stripe cutovers, and paywall-safe Nginx caching.
We recommend reviewing each GhostPubCalc architecture dossier before provisioning a node so your 4 GB or 8 GB KVM tier matches InnoDB buffer requirements and Gmail/Yahoo bulk-sender DNS rules from day one.
Ghost v5 dropped SQLite3 for production and mandates MySQL 8, shifting memory planning from Node.js alone to InnoDB buffer pools and member event tables.
When a newsletter issue hits Hacker News or X, uncached Handlebars rendering can saturate Node.js 20 single-thread CPU within seconds unless Nginx intercepts anonymous GET requests.
