simultaneous downloads no longer working in 10.6

Hi Arctic Ackbar,

I too am having the same annoying issue after upgrading to 10.6 and it still continues to plague me even after the latest update to 10.6.1.7

I don’t know if yours does the same but mine starts to download the maximum three items (if I have three or more but its the same even if downloading just two items) and it starts to download all three but then only downloads around say 100-200kB of the other two and waits for the first to finish, then moves onto one of the semi-downloaded items.

It then repeats this for all the remaining items in the queue so in essence I might as well just un-tick the simultaneous download option as it seems to slow the one download and general bandwidth of my internet down.

Lets hope it gets fixed in the next update, however I won't hold my breath

I am also having this problem. Installed the latest update and still no change. If anyone has any ideas, let us know.

1gbs fiber optic connection so speed isnt the problem. All started when i installed 10.6

I am experiencing exactly the same issue.

I thought it was something I had done as when I first searched for the issue I couldn't find any reference to it. I have also tried reinstalling with no joy and, like you, don't want to remove and reinstall.

I am seeing the same problem. Is Apple aware of the problem and addressing it?

Sorry to say but it's happening to me too!

Me too. I'm trying update my matched songs (from itunes match). Do you know how long it take to download 3k songs one by one? A lot longer than when multiple download at once!

I too am having the exact same problem.

I am on Windows XP, running iTunes 10.6.0.40, and will add my name to the growing list. I will also add that I tried doing an uninstall/reinstall of iTunes (a major headache itself) and I still get the error. I have had to uncheck the Simultaneous Download option since some transfer take so long that the 2 other "downloading" items time out and have to be manually restarted. By unchecking the box, at least each of the files does get a chance to download without a bogus downloading message timing out. I have not seen a response or comment from Apple about the problem anywhere on the net.

'Me too' Windows XP SP3 a variety of itunes versions up to and including 10.6.1.7.

It also appears to effect scanning for updates in my podcasts takes much longer than it used to and 'gets stuck', kind of like you would expect if it was serially trying each one before moving onto the next one where as previously it looked like it would have multiple requests in parallel and if some got stuck being slow to trespond the others would continue.

I have also notice this when updating apps, is it only affecting windows version of itunes?

I have not been able to test on Apple equipment. I can only confirm Windows iTunes having the problem.

After you wrote about this, I checked on my machine. I am not sure what the correct process is supposed to be, but on my machine when a refresh occurs of something like podcasts, they all queue up, three will show active icons indicating refresh, but only one of the three will actually progress at any time. So this appears to be more systemic than I originally saw. Both refresh of lists and the subsequent downloads are both "single-threading".

I haven't been able to do simultaneous downloads for a long time now. Every time I enable it I started getting "network connection reset errors". This still happen in iTunes 10.7. It's really annoying since it used to work fine. I'm running with Windows XP SP3.

I enabled simultaneous downloads in iTunes 11 and all my apps actually downloaded without error. I only had 7 updates though so I don't know if that was a fair test.
