I hope to find some way of improving iTunes performance or a better solution than iTunes for managing my large music collection.
I have iTunes Music Library.xml = 479 GB (on SSD boot drive)
Song Files (mp3) = 216,903 (on 3TB internal Hitachi Deskstar 7K1000 via SATA 3.0Gb/s on MOBO)
Latency is a very big problem for me.
I have tried many things:
+ Upgraded to faster PC, more RAM
+ Defragmented hard drives
+ Switched to SSD boot drive to speed up read/write of iTunes Music Library.xml
+ Disabled 'live updating' in smart lists
etc.
Nothing really helps very much.
Seems like I've spend half my life waiting for iTunes to handle mouse clicks - then when it finally responds, it sometimes handles mouse clicks in the wrong order. Miserable.
I would almost be willing to switch (back) to Mac (ditched it and switched to Windows back when OS 9 couldn't support long file names) but I notice that Mac users with big libraries seem to have the same latency / scrolling problems that I have.
I know the problem is the size of the library xml file but that is partly because I'm an obsessive catalog freak: I research data constantly, adding details of all the sidemen on each track, etc.
My guess is that iTunes is hopelessly doomed.
XML is probably the problem - a scalable library app probably should run off of a separate dedicated database.
