To have the rest of the page load and then the feed display later, you'll have to use AJAX to pull in a separate CF page clientside. (You'd still use caching in the feed.cfm so it'd only be slow occasionally.)
Another approach would have the feed fetching functionality in a separate template which is run as a scheduled task every 2 minutes. That task can shove the parsed (and potentially formatted) feed into the application scope. (With a lock.) And then your main page can output that variable (with a lock). Then your home page would load as fast as it would as if the feed were local.
