Current performance:
* a song Scms model is computed in 1462ms
* a playlist over 16000 tracks is computed in 2839ms

Possible speedups: Use multithreading for feature extraction: Issue #17

Computing an scms model just got faster (revision 91), decoding now is the
slowest
element in the feature extraction chain:
Mirage - mfcc Execution Time: 37ms
Mirage - scms created in: 18ms
Decoding/Downsampling/FFT: ~ 1 second (for MP3s)

Awesome !
Analysis and playlist generation both feel much faster.
I don't have numbers for before the changes, but here are my numbers with
latest svn
and a library of about 2000 tracks:
Decoding : 1470ms
Mirage - mfcc Execution Time: 28ms
Mirage - scms created in: 13ms
Mirage - Total Execution Time: 1569ms
Mirage - playlist in: 207ms
