There is an interesting article titled "Please Don’t Share Our Links on Mastodon: Here’s Why!" about the startling load that Mastodon's mass-distributed link preview generation has on small independent webservers. But I cannot link it to you, because of a reason
@mcc the confusing thing about that post is that they are using CloudFlare as a cdn but it apparently doesn't help? Either they or Mastodon are doing something really wrong for that to be the case.
@megmac @mcc Cloudflare as a CDN can't help you if your content isn't posting with caching headers that allow Cloudflare to actually cache requested pages, instead of just forwarding all the requests back to the source server.
@chris @mcc yes, hence either they or Mastodon are doing something wrong because opengraph previews should be served with caching headers.
