My itunes is running incredibly slow lately on my Mac?

Yeah. On my Mac. It's not even a Macbook Pro. It's a desktop. It was running perfectly fine up until 2 or 3 days ago and suddenly… Kaput. It's updating info extremely slowly, it's taking FOREVER to sync even 2 or 3 albums to my iphone… (as in the upper side of 45 minutes) and I have no idea why. The memory space is 1TB with a little over 225 gigs left available, I have 199.23 gigs of music in my itunes (almost 80 days worth), and that hasn't been a problem at all so I really don't know what's going on.

  • Why the hell is my NEW iPhone 4S running so SLOW? I got it a little before Christmas, it was brand new, AT&T 4G. It wasn't like this before! I barely have any apps, I have almost FULL bars and Wi-Fi connection, I don't know what's going on! When I'm on FB, it runs incredibly slow as well as on the internet. All I know is that it's p*ssing me off!
  • Why are people getting my texts incredibly late? - 1 Recently people have been getting my texts like 5 or 6 hours after I send them. Sometimes it's a duplicate of a text that they already received from me and they get it again hours later. It's obnoxious because they'll get a random text from me from hours ago hours later. I have an iPhone 4 with Verizon 3G, I usually have poor service but should this really be happening even under poor service? Recently I've been getting a lot of message send failures too
  • My iPhone 4 is running so slow? Ever since the ios6 upgrade my phone has been running super slow! Everthing takes so long to load like if I'm uploading a pictures or just refreshing twitter or even using the Internet it has been taking so long to load anything I even deleted apps and its still slow what can I do to get it back to normal again?
  • My computer is running slow? So I never had this problem until a few days ago. My computer (Asus windows 7) is running slow, yet if I go on my iPod or iPhone which is connected to the Wi-Fi in my house, it works perfectly fine. What should I do?
