The story
Nadia has been publishing weekly for four years. The site is a deep archive: two hundred episode pages, each with show notes, links, and a full transcript that doubles as the reason people find her in search at all.
Two things were slow. The archive, because a four-year back catalogue is a lot of pages nobody had thought about since publishing them; and the RSS feed, which every listener’s podcast app polls on its own schedule, generating the same XML from the database over and over for an audience that is mostly machines.
Caching the feed alongside the pages removed a surprising amount of load — the feed was quietly one of the busiest endpoints on the site. The archive is prewarmed, so an episode from 2022 that someone finds in search answers as fast as this week’s.
