Hello, I'm having some issues with my iMac I can't seem to figure out. Here are the specs:
27" iMac 2.8 GHz Core i7
8 GB 1067 MHz DDR3 RAM
1 TB 7200 rpm HD
Networked via GB Ethernet connection
Use Safari for most browsing (v 5.0.3)
Over the past few months, I've noticed the networking performance on my machine has been considerably slower than when I bought it. Internet pages take much longer to load, streaming video is basically out of the question at this point, and my Time Machine backups to my Time Capsule were taking much longer than they used to. The first thing that I noticed is that my Time Machine icon seemed to be perpetually spinning and indicated it was indexing the backup. I'd heard that the Time Capsule's performance can sometimes be affected by being in an enclosed space due to heat, so I moved mine to a more open area to where it could breath more effectively. When that didn't help, I stopped automatic backups to see if that would help. It did nothing for me either. I've created a new user account to test to see if that would help, and I'm experiencing the same issue. I tried quitting every application that uses an internet connection except for Safari, and that didn't help either.
My system shows almost no network traffic any time I'm on it, and activity monitor shows almost no processor usage either. The rest of my system is still fast when opening windows and applications and such. I also don't think it's my internet connection, as I had a MBP for work that I use at home from time to time and the internet connection on it works flawlessly.
This leads me to believe there is some kind of virus/spyware on my machine that's slowing it down. I installed Sophos and it's been running; it found and killed JS/WndRedB, but that hasn't helped either. The only other oddity I've found is the amount of data sent. I've had my computer on for about 11 days straight now, and in that time, I've received a little over 2 GB of data but have sent out almost 12 GB. I find it hard to believe that I as a user have actually needed to send out that much data.
Any suggestions would be appreciated, and let me know if you need any more information.
