Itunes on NDAS, recently experiencing large network traffic increase, flooding.

Asked by pacoroban (1points) March 5th, 2009

I moved my iTunes Library a while back to a XIMETA Disk Drive accessed through ethernet. Everything worked fine, until I began noticing delays in playback. It sounded like a CD skipping if anybody is old enough to remember jogging with a portable CD player.
I check the drive, the disk, and the network traffic. I noticed that everything was fine but the network traffic was at a maximum, when it really should be at 0, or idle.
I don’t have a network sniffer or the knowledge to use one.
I can’t tell from the process list which is consuming more CPU power, there are a number of them consuming 10–20%.
If I remove everything from the problem I’m left with iTunes and NDAS. Anybody know of a remedy to iTunes running a lot of network traffic when using a netdisk

First of all; it’s unlikely that this activity is hurting anything or degrading performance on your network. (If it’s bogging down your computer, then you might have issues in the computer itself: low RAM, slow antivirus, too many “helper” programs running, etc.)

Two most likely possibilities with networked disk storage (“networked [direct] attached storage” or NAS or NDAS):

Because your computer OS thinks of these disks as being “directly attached”, then your anti-virus or anti-spyware programs may think of them that way as well. If that’s the case then the high network activity you see may be due to a scan of the data on your networked drive.

Another possibility is iTunes doing some maintenance task or other. That could be anything from a “Genius” update to a playlist backup to just a routine scan to make sure the iTunes database is up to date.

Again, if your antivirus program is scanning data here, then you may want to go into the “Exclusions” settings in your AV program and tell it to ignore data that is in your iTunes library folders. (Note: don’t exclude the file types—.mp3 and such—just the exclude the folders. That way the song files will be scanned on their way in to the library, or if you play a track from some other source.)

If you think that it’s iTunes and you want it to stop; then change the iTunes settings so that it doesn’t load up automatically when you start your computer or plug in your iPod, but will only start when you expressly command it. It will still do those things, but now it will only do it when you load it into your computer.

Hope this is helpful.
