Advanced settings (Collection)
- 
 In Settings>Collection>Advanced there are three settings: I/O priority (default "Idle") 
 Thread priority (default "Idle")
 Tagreader workers (default "1")Could you give a brief explanation of what these settings do, and any cautions that must be considered before changing them. I have a fairly large collection (185,000 songs) and the search function chokes now and then. I have plenty of RAM, but my CPU is pretty low powered (Intel Core2Duo) and I'm looking for any advantage. Wondering if these Advanced settings would help.

 These settings are for the file watcher/scanner, not for the search, so changing them to a higher priority will probably make it worse since the GUI might lag.
