Only a cache with possibilities of the server was used higher as 2.6. The functions in xore have the same name. I hope, i understand your comment right. @DD32: i think, WordPress use not a filebased cache with the version 2.6. Only a cache with possibilities of the server was used higher as 2.6.

Transients are like options, Which are only stored in the database if(and only if) an External Object cache is not loaded.

Not sure what you mean by that.. The API and underlying structure hasnt changed since nearly 2.0 IIRC. Its just that recently, The file-cache was striped out of WordPress so people wouldnt enable it on some hosts..

It is Persistent if someone loads an External Object cache.

Transients should be used.

So it only make sense if some data has to be used few times in a single page load. To cache between page loads - options and transients should be used. PS fetch_rss must die, long live fetch_feed :) One thing I don't see in post and found confusing - this cache is not persistent and only stays in memory until page is generated.
