iTunes NAS Latency

[teknovision]

Hi all!

Haven't been having too much luck with iTunes 7 and NAS, it seems like iTunes is extremely slow suffering from the Spining Beach Ball very often i.e. after launch of iTunes, when dropping new folder of tunes, adding info to tracks via 'Get Info'.. .

I uninstalled it (including all plist and library), rebuilt from scratch, uninstalled and installed iTunes 6 (no problems there) and recently re-installed iTunes 7.02 in the hope that something might have been fixed.

All files are stored on the NAS and library is stored locally. It seems that once NAS has been unmounted, spinning beach ball disappears so it really does seem as this is a NAS specific issue. Anyone have any tips/suggestions or do I have to wait until Apple release fix - just bought new nano otherwise would have stayed in iTunes 6.x?

Many thanks,

How big is the Library?

[teknovision]

The xml library file is about 11mb (stored locally), about 9000 files which comes to 80Gb on the NAS.

has it gotten thru doing the Gapless song reads?

Is NAS connected through ethernet all the way or wirelessly to your Mac?

Right have tried iTunes 7.02 via ethernet, no problem my iMac does the whole gapless and 'Add Library' in about 15 minutes! My iMac however which is connecting to the NAS over two Airport Expresses takes days (not joking) before it completes gapless. Aiport Express seems to be at fault here any dieas what I could do other than go and and buy 15m of ethernet?

Any help is muchlyt appreciated, apologies in delay in replying some reason never got notification that I had a reply!!

The bit rate on airport (802.11) can be much lower than ethernet. Even though the maximum speed numbers look reasonable, in practice you end up getting much lower rates. If you are going through two of them, it is probably even worse. NAS itself might also have some protocol overhead, although I don't know much about that. I think buying a long cable might be your only option.

I tried to increase multicast rate and that hasn't really done anything for it, what is really odd is that it worked just fine in iTunes 6.x.

I've looked at using power/electricity to network, it just seems crazy to have to spend more because Apple didn't test develop product properly to work with it's own periperals.
