iTunes 12 extremely slow?

I have the same problem, iTunes has slowed down to a crawl, spinning beachball for minutes, "application not responding".

I use a MacPro (late 2013) with 64GB of RAM, the iTunes library is located on a Promise Pegasus NAS (28TB), my library has a size of 7.03TB (over 238'000 items), the NAS is attached via thunderbolt, almost all files are "apple lossless".

This is a pain in the ***, whenever I try to use the search function, the spinning beach ball pops up and iTunes virtually freezes, same whenever I switch to a different view (from songs to albums for instance), basic stuff so to speak.

I tried to create a new library (re-importing my music files to a new library file), I started up in safe mode (made no difference), so I am stuck. Apple should address this problem asap!

Ye. I have pretty much the same issue after the new Yosemite update. It shouldn't be caused by the size of the iTunes library, mine is not that big - about 1200 songs and there is a delay every time I try to skip a song.

Echo for this problem. I have a MacBook Air, 8Gb ram, i7 processor, so I don't believe it's caused by lack of hard ware. My library is relatively large (300Gb), and access via my home network, but with iTunes 11 it was ok (I wouldn't say fast, but it was useable) now with iTines 12 it is pretty much unuseable - 35 minutes to add tracks to the library, 17 minutes to add 10 tracks to my phone...

I am extremely unimpressed, but have not found a good solution so far.

Worst itunes ever! itunes 12 is even slow on relatively small libraries. Mine is about 250gb, and I get the beach ball on basically everything I do, everything from adding tracks to selecting songs to play. I'll be be reaching out to itunes about this.

I have a large library, but I also have a very fast Mac - 6-core 2014 3.6 GHz Xeon E5 Mac Pro with 32 Gigs of RAM.

It took 45 minutes (I am not making that up) to uncheck the "Show iTunes in the Cloud purchases" box. Even the most simple tasks take a few seconds of beachball or more.

The last few major iterations of iTunes have started out slow and then improved somewhat with revisions, but this one is shockingly, lamely slow. Almost unusable, and for some tasks, unusable, period.

26 seconds to switch from the iTunes store view to the Playlist view - again, on a 6-core 2014 Mac Pro.

Late 2012 entry level Mac Mini. Switching between songs can take up to three seconds in some cases, which is completely inexcusable in this day and age. It'd have been inexcusable in 2004 even.

Overclocked PC at 4Ghz 16mb Ram. SSD. Itunes 11 was abysmal - terribly slow. 12, well, it's even worse. Over 30s to start. music library is less than 64gb, no videos.

Click and wait the whole way through after it opens. It's a cosmetic upgrade with no attention to function whatsoever.

This is the slowest iTunes ever! It's EXTREMELY slow when using the keyboard. I just switched to Spotify even if I don't like it. NICE job Apple I'm also having the same problem with Safari for back/forward gestures. It's not logic to reload every page for every back/forwards gesture. Maybe I want to go back 3+ steppes? Should I wait for the two other pages to reload before I can see the third one?

APPLE WHAT THE ****? IS THE ISSUE EVEN TESTED? HOW CAN YOU RELEASE A APP WITH SUCH A ISSUE?

Please, how can I as an Apple-fanboy promote your products when I've stopped believe in them?

I was struggling with this and doing all kinds of research online. I just discovered that my computer was perpetually trying to sync with my iphone. I just turned off the wifi on my phone and the computer is now functioning fine, itunes included. I recognize that this is not a permanent fix as I do need to use my phone's wifi at times, but at least I can use my computer now.

I had an issue a little similar to this. My iPad Air took 30 minutes to sync through cable to iTunes. I used this note

iTunes: How to re-create your iTunes library and playlists

to reindex my iTunes on my iMac running Maverics. After recreating iTunes indexes and whatever, my iPad Air (original) running IOS 8 now sync within e couple of minutes. I have approx. 400 apps on my iPad.

My old iPad 2 and our iPhones 4S and 5 were NOT slow. Only iPad Air.

Perhaps some reindexing of iTunes internals is the problem for you.

This is truly one of the worst variations of iTunes ever, it's as if someone ran to get this out to the public with out testing it first. I have been trying to sync my iPhone for the last thirty-five minutes and it is still not done; my normal sync times had been in the ball park of two to four minutes depending on how much has changed since the last sync. Now I don't know if I'll ever sync it again, at least not until some patches this version or wait for unlucky 13.

I tried re-importing the iTunes library and I can't recommend this solution.

1. It didn't solve the problem. iTunes was still freezing/slow afterwards.
2. It took more than four hours (how much more? I don't know; I went to bed.)
3. When iTunes finished the import, it threw an error saying it couldn't find all my songs.
4. After completion, Time Machine decided a large portion of my 3.6 TeraByte library needed to be backed up again. 833 GB, to be precise.

My library is a little over 80,000 items and iTunes takes 10-15 minutes to mount the iPhone 4 and iPad 2. Synching my iPod Classic takes forever, even when I am not adding/removing media. A sync that used to take 45 seconds is now taking 5-10 minutes. Most of the iPod Classic sync time is spent "checking for tracks to update".

iTunes 12 has been a disaster for me. How do I downgrade to the mildly crappy iTunes 11?
