I have strange problems with the rss-feed from serienjunkies.org (the feedlink is http://serienjunkies.org/xml/feeds/episoden.xml).
- Compared with Google Reader, not all elements seem to the find their way into the database
- filtering/searching/updating is rather slow
Second point could be due to rather high volume (~ 100 items a day) and running tt-rss on a AMD E-350 (slightly faster than Intel Atom). Displaying just the unread items as fast as for all other feeds.
