Why is iTunes is extremely slow to sync suddenly?

Recently iTunes has become incredibly slow to sync. While syncing to my 1st gen iPad, the app is making progress but it is soooo slow. Trying to interfere results in beachballing. I seem to have noticed the change after two recent things have happened.
First, I started using iPhoto and syncing photos to my iPad, where before I was just syncing a few photos direct from a Finder folder. Second, was the most recent iTunes update. Note that all of iTunes is slow as soon as I hit sync - it is not the photos portion holding up or their initial optimization. Also, I synced photos after I started using iPhoto successfully a few times before this happened, which makes me lean more towards a problem with the update perhaps?
I am running Lion on a 2008 iMac. Everything is up do date.
Any suggestions? Thanks in advace.

Apparently it's something related to the external HDD (500GB WD MyBook) which stores all of my iTunes music and movies. Everything syncs when I disconnect the HDD. I still haven't solved the problem, but I can at least sync photos/apps/whatever else isn't on the drive, and have eliminated iPhoto as a possible cause.

Since the latest update, my iTunes is EXTREMELY slow. I'm about to turn to Windows. Can it go back to previous versions?

Slow in what respect? Please be specific.

Ummmm, could you ellaborate on how you plan to turn to Windows because iTunes (an application that runs on Windows) is running slow?

Itunes starts extremely slow after an update of windows 8.1.

Itunes starts extremely slow after an update of windows 8.1.
It takes up to 10 minutus.
If I see the appliction log in event viewer then I see the following errors on the Bonjour service.
For instance:
Client application bug: DNSServiceResolve(a8:fa:d8:3a:1e:8f@fe80::aafa:d8ff:fe3a:1e8f._apple-mobdev2._t cp.local.) active for over two minutes. This places considerable burden on the network.
followed by
SendWakeupPacket error: sent -1 bytes: 10065
What can this be?
Already thanks,
John

I did all the step with save mode and that didn't gave the same result.
Then I created a new account and there itunes started up normally.
So I contued with the user section.
I removed the itunes directory from
c:\Users\username\AppData\Local\Apple Computer\iTunes
This gave the same result in not starting up.
Then I removed the itunes directory from
c:\Users\username\AppData\Roaming\Apple Computer\iTunes
The a popup appears that the Bonjour Service has been disabled.
I looked in services and saw that is was still running.
But I tried to restart this service and it took a long time to stop this service.
Even if I selected restart the Bonjour Service didn't start.
Manually starting was not a problem.
Clicking OK on the popup let itunes start quickly. And closing and starting it again was also quickly.
So Matt thanks for your answer.
If it happens again I have to see if it was the removing of the itunes directory from roaming or restarting the Bonjour Service.

ITunes + Ping extremely slow with Library on external HD

Hi,
My Library is on an external HD connected to an Airport Extreme base station. My MacBook is connected wired to Airport, so there are no possible wifi connection issues.
iTunes is extremely slow since version 10. If I select a song and want to select another one, I've got a spinning beach ball for at least 20s. Change a rating: 20s delay. Every move I make: at least 20s delay...
My guess: every time I select a song, iTunes connects to Ping to fill up the dropdown menu next to the song title. Disabling Ping doesn't help. I tried in Terminal "defaults write com.apple.iTunes hide-ping-dropdown -bool TRUE", but this merely hides the dropdown menu, it doesn't stop the functionality.
iTunes is basically not usable anymore.
Any suggestions?

I am running iTunes 11 with the media files stored on an external hard-drive. This setup works great except for one thing:
If I am currently downloading something from the iTunes Store and I quit iTunes
Don't quit iTunes.
How can I make iTunes see the interrupted download and not have to restart the download from the beginning?
You cannot.

Why wont iTunes allow me to copy/sync a song from my iPod?

Why wont iTunes allow me to copy/sync a song from my iPod? I have a song on my iPod that i want on my laptop to add to my iPhone, but i can't sync it. I did not purchase it via iTunes.

The music sync is one way - computer to ipod. The ONLY exception is itunes purchases.
As the song came from your computer in the first place, it should still be there and be included in your regular backup of your computer.
The ipod is not a storage/backup device.

Why is firefox becoming extremely slow or stuck when choosing a website in win 7 64-bit pro?

when starting a new website from search or bookmarks it starts with connecting and collecting data from the requested website but it get stuck or is extremely slow. One solution is to click update button several times. Is there a way to solve this problem? I have tested both stable firefox 6 and firefox 7 beta. This is not happening in win xp pro or other windows xp versions. Internet explorer (64-bit) is working fine, but I want to use firefox.

Oh just so no one is confused I did not create this question on the actual laptop I am talking about (thats why it says my OS is XP)

ITunes is extremely slow and I cannot make a secure connection

When I connect to iTunes my computer is extremely slow, and when I try to connect to the iTunes store I get the error message cannot make a secure connection. I have internet access and I have ran the iTunes diagnostics test and all the tests passed except making a secure connection. I have disabled all of my security systems including my firewall and Norton. I am not running any proxy settings. This has been an ongoing problem for over a month and I am at a loss.

Check out this Apple article -> iTunes: Advanced iTunes Store troubleshooting
Blocked by configuration: (Mac OS X/Windows)
Configure Internet Options (for Windows computers only):
Run iTunes Diagnostics. If the "Secure link to iTunes Store" section does not pass, do the following.
Open Internet Explorer.
From the Tools menu, choose Internet Options.
Click Connections.
Under "Dial-up and Virtual Private Networking," choose "Never dial a connection." It may not be possible to choose this if you’ve never used dial-up Internet; if this is the case, skip to the next step.
Click LAN Settings.
In the window that opens, enable the option to "Automatically detect settings" if it is not enabled.
iTunes uses Internet Options proxy settings. Apple recommends removing proxy settings that interfere with access to the iTunes Store if needed.
Click OK.
Click the Advanced tab.
Scroll down to the Security section and look for the option to "Check for server certificate revocation." If it is enabled, disable it.
Look for Use SSL 3.0 and Use TLS 1.0. Make sure at least one of those two checkboxes is selected and click OK (You can select both checkboxes).
Apply any changes, and restart your computer if you modified the option to "Check for server certificate revocation" (step #11).

Itunes 8 extremely slow and feezes Vista

Oh my god,
This is getting worse. If you tought that Itunes 7 and Vista weren't ment for eachother, Itunes 8 and Vista just hate eachother. Itunes 8 is just extremely slow on my fresh installed Vista. It keeps freezing up and sometimes my system won't respond to a thing I am doing thanks to the wonderfull crappy software from Apple...
If this is really all you guys can write then I guess I will have to look for a better software to synch my ipod.

I've definitely noticed that switching between library sections (music, movies, etc.) is much slower in iTunes 8 than it was with ver. 7. So far, it's a teeth gritting annoyance at worst. It improved somewhat when I set all areas to List View, but only somewhat. The program also takes longer to load than version 7 did (sort of unbelievable in itself!), and there WAS one heart stopper of a moment where I thought it had locked up and taken my HP laptop with it, but it came back after 15-20 seconds on its own. I don't have a novice-level PC by any means; it's one of the newest and nicest of the direct-to-retail models, with a Core 2 Duo (P8400), discrete Nvidia 9600M GT w/512MB RAM, and 4GB of system RAM, running Vista HP 64 bit. (Yep, I installed the 64-bit iTunes.) I did notice one other poster mentioned having an HP laptop. Doesn't seem like hardware limitations should be a factor, at least in my case; I hope, whatever the issue turns out to be, that it isn't some total incompatibility with something HP loads on its machines. I'm sure Apple will come up with a bug fix at some point, but since the iPhone 3G became part of my life, it sure seems like a large chunk of that life is spent waiting for Apple to fix bugs and putting up with subpar performance in the meantime. I'm pretty new to things Apple, and I can say quite honestly that all the problems I've had with various iPods, the iPhone 3G, and here and there with iTunes were the reason I chose my current laptop over a MBP. I couldn't stand the idea of spending all that money and getting a lemon. Apple isn't the huge performer I'd always heard it was, not in my experience!

After 10.5.7 update, extremely slow home sync

After updating the server to 10.5.7, the 'full' sync at login/logout has become extremely slow. On a sub-spec Leopard machine like a 500MHz G4 it actually took 30 minutes to log in because of slow syncing. On a MacBook (Core Duo) it takes 15 minutes. It takes long checking, it is very slow syncing, and finishing takes another 4-5 minutes.
On 10.5.6 it was OK. Both clients have been updated to 10.5.7 client. Multiple login/logouts do not change anything. Logging out (15min sync) and immediately logging in results in another 15min sync.
Most of the time seems spent syncing of Library/PubSub. It may be just 1.5MB or so, but it takes ages.
I am using server side file tracking.
Anything I can try to do to make this usable again?

I first removed syncing ~/Library/PubSub but this did not help too much.
I removed the contents of ~/.FileSync from clients (2) and server. Since the clients have FileVault home dirs that requires being logged in everywhere.
The old SQLite db in ~/.FileSync directory was 16MB, the new one 1.8MB. After that, I have seem an improved responsiveness. Still not something extremely fast, but good enough.
It would be good if there was some sort of 'reclaim' functionality in the SQLite db that underlies home syncing, just like there is for FileVaulted home directories.

Why did iTunes delete 2000 photos during Sync, even with 1 GB free space

I am having real headaches with Sync function in iPhone/iTunes. The 2 biggest problems concern Contacts and Photos.
Photos: I used to have 4465 photos on my iPhone, using 1.47 GB at a time when my iPhone still had 0.67 GB free capacity out of its 29.3 GB total. About a week ago, while syncing with iTunes, I saw the error message on my PC stating that there is not enough space on my iPhone to copy all photos. At the end of that sync, I was left with only 2072 photos using 0.78 GB, while the free capacity on my iPhone increased to 1.6 GB. I have synced at least 10 times since then to try and recover my photos, I have deleted the 2.4 GB photo cache, but exactly the same error message and issues happen. Please help get my photos back into my iPhone!!?
Contacts: my iPhone is the principal device on which I put new contacts or update existing ones. After syncing, sometimes I see that the new information entered into my iPhone is no longer there. And so I lose contact with people, since I have no other records! That’s really frustrating.
I have tried upgrading my iPhone software from current v4.02 to the latest v4.1, but for the 5 times that I have tried my WiFi has timed out, and so still not upgrade, as Murphy Law would have it!

I guess I should have included a little more info:
1. I only have 1 appleID
2. I only have 1 apple device (the one iphone, nothing else)
3. I only sync on one computer (VERY annoying you cant use more than 1!!)
4. I never have any other problems during syncing and don't change any settings
5. I downloaded the app again so it is back.
I am not asking how to get the app back, I just want to know WHY itunes deleted this app. This is the second or 3rd time it has happened and it is really annoying.
I also would like to get my files back. So again, I'd like to know why itunes deleted the app and if it deleted my files as well.
The most important part of this is to find out WHY this happened so that it wont happen again. It seems to be a pretty simple operation: Plug the iphone in, itunes opens and does a sync. It almost always works perfectly, I never change any settings. Yet every once in a while it deletes a newly installed app so obviously something is wrong. If I can find out what I did wrong, then I can avoid it in the future.
Thanks!
Scott

Itunes is extremely slow

After I couldn't open up Itunes for months I finally got it to launch but it's extremely slow. When the music store finally displays it has broken chains for pictures and it responds very slowly. Not doing what I tell it to. The fact that I can't call Apple is extremely disturbing, but I've done my part by telling people not to buy an ipod and get an mp3 player instead.
Help would be appreciated, thanks.

Reinstalling iTunes shouldn't lose your music files.
But it is ALWAYS a good idea to have backups, esp of purchased files.

Why does itune delete my pdf when syncing?

Hi,
I'm just got a ipad air 2, and I'm totally new to apple both software and hardware. One thing I don't understand is why does iTunes prompt to delete my existing pdf in my ipad which I download from my email when I sync up with itune where I had some other pdf? (under the ibook)
from a logical point of view my understanding of the word "sync" is to ensure both side (ipad and itune library) had the same data or files when there is a different in data/file. (correct me if i'm wrong)
pls advice on how to do a sync which ensure both side of data is same why syncing. as I travel around I don't always keep my doc in the itune computer.
IPad air 2 ios 8.1.2
regards
Soong

Syncing is from a computer to a device, when you sync it takes what you've selected on the tab in iTunes and replaces what you've currently got in the app on your iPad with that selection.
You should be able to copy them over to your computer's iTunes library via File > Devices > Transfer Purchases (though they aren't iTunes purchases that should copy PDFs and/or epubs in the iBooks app on your iPad) - and if your computer is a Mac with Mavericks or Yosemite on it then do File > Move Books From iTunes in its iBooks app to move them over to it. They should then show on the iPad's Books tab for selecting / syncing / keeping on the iPad.

ITunes Store extremely slow...

There are moments (often) when the iTunes Store is just extremely slow. I'll buy a movie and it will tell me it'll be ready in 3 hours. How am I supposed to watch anything on my iPad or Apple TV?

The widgets weren't working either, clean installs seem to fix everything, even if they take several hours.

Safari 3.1.1 Extremely slow startup times (Suddenly)

Hi I'm running a Macbook with a 2.4 GHz Processor, (Intel Core 2 Duo), 4 Gigs of ram and Mac OSX Leopard 10.5.3.
this mac is about 2 months old and suddenly am having extremely slow startup times with Safari. The rest of the computer is very fast, this problem is only with safari... It used to open with about 2 or 3 bounces on the dock... now suddenly its around 15-20 bounces before it opens. It bounces this many times, and then I receive the beach ball for a few seconds. I am assuming it is probably a build up of some files, or tasks it runs through to open... It is worst when you open it for the first time after powering on the mac, after you open it, and close it it opens up a bit faster.
I have tried the basics, i.e. resetting safari and things like that.
Most of the suggestions for deleting files out of the User>Library> are for older OS's and do not apply to Leopard...
Any suggestions?

Navigate to this location: Macintosh HD/Users/YOURUSERNAME/Library/Preferences and delete the following files:
com.apple.safari.plist
com.apple.safari.RSS.plist
Do this with Safari NOT running. See if that solves the problem.
