The index page of my rails app grabs an rss feed from a neighboring news
site. Unfortunately, the process of grabbing that feed seems to be
slowing down the initial load time of my site to the point where it
takes about 10-12 seconds to respond and render.
I’d like to speed that up somehow (for 8-10 seconds it looks like my
server is not responding at all…) Any suggestions?
But as soon as I modified my controller from < Application to <
ActionController::Base it stop rendering my page (which I guess is
expected but I have no idea how to workaround that.)

can somebody please help me with this?
The way I do it is to have a table/model for the feed_items, with a
created_at field (and also a feed model, which has_many feed_items).
Then in the Feed model I have a update_feeds class method which first
checks when the most recent feed_item for that feed was updated. If it’s
less than 20 minutes ago(if !f.checked_at || f.checked_at <
20.minutes.ago), it checks the feed again; if not, it returns the
feed_items from the db.
The method’s a little more complicated than that, so it doesn’t replace
feed items it’s already got, but that’s the basic idea.
