Bug Description

Elementary OS (0.2) delays around 10 hours to add my library in Banshee and just add 252GB. Noise not work and Spotify just add 27gb. In Windows or Ubuntu, works fine.

Sorry my bad english. :/

PS: i have 278gb in my media library. Just mp3 and all my collection is in a NTFS partition.

I too have the same problem. I am adding music to my library in the music app which is taking very long and it is freezing too.

Ok, here is some news about the issue.

Noise is still having some problems, but I'm able to listen to music. The problem is now that is too slow to import a big music library (~140Gb of music files, some in mp3 and the others in flac). Rhythmbox completes the scanning in less than an hour. I have an i7 (notebook) and it uses ~95% of one of the cores of the processor, and slows the response of the OS. This is not a problem on it's own, but it's a core used at high load for really long time, so it becomes a little anoying. PD: Sorry about my english, I'm a little rusty.

Noise users reported something very similar with respect to slow library write speeds: http://elementaryos.stackexchange.com/q/7638/5565

One commenter raised that the slow speeds were due to single-threading vs multi-threading

Hi! I think we can merge this two reports. It's possible to do so?

This is still happening as of Elementary OS Juno. I have about 300gb library and it's been scanning all night and still hasn't completed. The program is close to unusable while this is happening. While scanning it's using about 25% of one cpu.
