@galaxis @aral There are ways around it, though. Leaner feeds (don’t go back far in time), add pagination via https://tools.ietf.org/html/rfc5005#appendix-B and make sure client and server use HTTP caching (simple use of if-modified-since headers and 304 responses). These already help a lot. The next step is caching the RSS to a file and letting the web server handle it. I had to do all this for Emacs Wiki, years ago.
