Updating library from Plex

When starting Infuse, the update from Plex takes almost an hour (about 2800 movies/21000 tv shows/very powerful Plex server). No new movies/shows is discovered/shown (as far as I can see) until the update is finished. The Plex app shows new items almost immediately, is this something Infuse could do as well?

Incremental new movies takes a few seconds to show up in Infuse, apparently Infuse downloads its own metadata. The plex client does not so I suspect thats the difference for large new scans.
