GPM sync slowed to a crawl again [#16431]

Currently is taking approx 20 seconds per 100 tracks ... 1st sync; options: Scan GPM, and "Only Include matches" options selected ... Download and Sync metadata not selected

I think the previous benchmark for approx 60,000 tracks was < 10 minutes
The previous release had blown out to an hour
Version 2230 is roughly 3.3 hours.

Link to partial debug log PM'd to Ludek.

I cannot replicate (in my case it scans 10000 songs in 2 minutes), but I can see in your debug log that it is really slow for you and some simple DB operations that usually takes just several milliseconds takes even 7 seconds on your DB now (for some unknown reason).

Could you please share your current MM5.DB with me? i.e. PM link to your DB? Thanks!!

FYI: I found the reason and fixed it as https://www.ventismedia.com/mantis/view.php?id=16431
So should be much faster in 2232
