Summary0022321: Building sync-list is slow for specific auto-convert rules (regression)
DescriptionUser from ticket [Ticket # 18353] is experiencing very slow analyzing phase of sync process..

I have analyzed the log and the slowdown is caused by the fact that for some reason MP3 tag is read for every file on the sync-list.
I've done code revision and found that this can happen for some specific auto-convert rules. This was added recently by Michal and thus is regression.

This needs to be optimized.
TagsNo tags attached.
Fixed in build3522

Fixed in build 3522. Scan now saves stream info even from MP3 or WMA, so additional file analysis should not be needed during sync for these formats. Also detailed format is requested only if really needed now, it was requested too often unnecessarily.
Only note - old DB does not contain this info yet, so first sync of the files still could be somehow slower, but info is added and subsequent sync should be already fast.
