Hi,
I found some time to run some tests with the new scanner.

Amarok from git master of today:
Full rescan with the collection already being present on the external 
MySQL database.

- 11:30 mins for the first scanning part (up to 50% in the progress bar)
- 2:50 mins for the last part (remaining 50%)

Total time: around 14:20 mins.

tracks found: 21113
albums found: 1703
artists found: 1013



Amarok from commit 7de53dd9976b978c8b02448fcaf4e554d4902650 (old scanner):
Full rescan with no previous collection, using an external MySQL database.

- about 10:05 mins for the whole process.

tracks found: 21113
albums found: 1701
artists found: 978


The old scanner is faster.

The new scanner also has some bugs like:
- most covers are not detected.
- some wrong Various Artists albums. I guess this could be the cause of 
the different albums/artists count.

Ralf is aware of these bugs, I hope for a fix soon.
Then maybe some optimization to decrease scanning time would be good :)

Cheers,
Mikko
