Huge and slow feed

Moin!
My feed http://einschlafen-podcast.de/feed/aac is quite huge (almost 1MB) and quite slow (Hosteurope WebPack). Currently, the Overcast.FM server crawls fails with a time out. Might be the feed is just too slow. Is there any caching for the feed, or are there possibilities to make it smaller/faster?

Thanks,
Toby

You could use paged feeds. Go to the “Podcast Feeds” menu of the Wordpress plugin and select an item limit for the feed. The problem with this of course is that some podcatchers don’t support paged feeds, so users will encounter problems accessing older episodes.
