Best way to setup database on NAS?

[misplacedamerican]

I have been using MM for years now and have not found an answer to the configuration question yet.

If someone is using MM and has a half decent performance setup I would love to know about it. I accept that there are performance issues, but someone must have a workable solution.

I am using 3 machines running Windows 7 they are a mix of wireless and gigabit ethernet
I have a QNAP 809 Pro to store the music files
I have 2 Logitech Slimserver devices to stream music via the QNAP to my home
I have 2 Popcornhour devices to stream movies and music through the house
I use MM to manage playlists that I upload to the Slimserver/Popcornhour and also sync the ipods/iphones in our house.
I still begrudgingly use iTunes to backup the applications on the iPhones until there is an alternative solution

The performance of all of my other devices has a few niggly bits every so often but for the most part performs as expected. All the machines in our house were running XP until the version 7 came out as we had several problems with Vista, I didn't have a performance issue whilst running Windows XP but then I had PLENTY of other issues not MM related when using older versions of Windows such as drivers.

When trying to troubleshoot the performance issues, I have tried several "Google tips" to reconfigure my Windows 7 network settings with the intent of improving speed. No help

I have tried storing separate DB's on the individual machines with the music on the NAS, I have tried storing a single DB on the same NAS as the music after editing the individual ini files by adding the db location. I have tried installing MM locally; I have tried installing MM centrally on the NAS. I have not found any significant performance improvements; granted it is slightly better with a local DB file and wired connection but then I have to make the change to each of the PC's individually or copy the db files across after every change and run a wire to every laptop.

The scan of my music director takes on average, 2 days, heaven forbid you want to use MM or sync an ipod/iphone while running a scan. Guaranteed to freeze and you have to start from scratch.

I am a huge fan of MM but this performance issue is making it close to un-useable

Has someone got a configuration running that has acceptable performance? I am desperate not to have to run iTunes in the meantime...

Please help
