Using build 95fdad5.

The database on the Clip+ is very slow in loading: when you select an artist/album/..., it takes about a second or two for the list of albums/tracks/... to show up. On the latest stable release this is instant. This problem has likely been around since;a=commit;h=7d1a47c
This task depends upon

Yea, quite possible that has something to do with it. You said "likely" but didn't confirm. Yes, it disables some code for caching dircache pointers for the time being because of the dircache changes so, as a result, I wouldn't at this point consider it a bug but just a prompt to continue the project.

ETA: I haven't noticed that short lists take much time to populate. How many items in a list a we talking about?

Opening the artist list (like pretty much everything else) is instant, but once you go a level deeper, i.e. to albums by a selected artist, the list of that artist's albums doesn't show up instantly but takes a noticeable amount of time, however the amount of items in the list doesn't seem to have a large impact on this as a list of 1 item and a list of 40 items took about the same amount of time to show up.

Also, possibly the most noticeable slowness is when adding anything from the database to a/the playlist. On the last stable build, this is instant (adding 1000 songs takes less than a second), but on the daily builds this takes a lot of time (adding 1 song already takes more than a second, adding 1000 takes excruciatingly long, about 20 seconds at least). However, this slowness in adding to playlists only occurs when you use the 'add to playlist' menu option. When you just click on one of the songs to start playing, the playlist is instantly populated with all the album's tracks.

Hopefully this has helped a bit in finding the cause.
