[...] So, I started to search and ask how often the fetch feed function pulls in the new feeds. I could not, however, find an answer to my question. That’s because I was asking the wrong question. The WordPress feed cache is what determines how often the feed is pulled in. In my search for answers I finally found this article by WP Engineer – Feed Cache in WordPress. [...]

Hmm... ok thanks Frank.

Not a fan of caching RSS feeds to DB.

@r-a-y: to the DB, table _options, not on webspace in a directory

Anyone know if wp_feed_cache_transient_lifetime is global and applies to all feeds, or whether it can be used a on a per feed level. Such as: add_filter( 'wp_feed_cache_transient_lifetime', create_function( '$a', 'return 1800;' ); $feed = fetch_feed( 'http://example.com/feedurl' ); remove_filter('wp_feed_cache_transient_lifetime', 'hourly_feed'); //Next Feed with diff. cache time add_filter( 'wp_feed_cache_transient_lifetime', create_function( '$a', 'return 4800;' ); $feed = fetch_feed( 'http://example.com/feedurl' ); remove_filter('wp_feed_cache_transient_lifetime', 'hourly_feed');

Thanks for this post! I started using the fetch feed function to display delicious bookmarks feeds with specific tags in the footer of my site. I couldn't figure out why the feed wasn't being updated even though I had added new bookmarks with that tag.

I found your article, added the add filter to my functions file and now the feed is being updated.

Does the new SimplePie library in WP 2.8 cache to the DB or to a directory?

I'd rather RSS feeds cache to a directory.
