Every since I upgraded my OS to 10.9, my performance has been going downhill. Now, even though I have reformatted my hard drive and have not even put any new data on it, it takes 45 minutes to restart and 25 minutes for me to open the window to write this message. Below is my system info. If anyone has any great ideas or reason why my system seems to have slowed down so much it would be greatly appreciated. You can see there is nothing on the hard drive to slow it down.

There should not be question marks after the memory complement in the About This Mac box. Either you have some unusual kind of system corruption, or (more likely) the memory is faulty.
I was wondering about those Question marks. Unfortunately I live a long way for any Apple Store. is it worth it just to order some new RAM and try it out or should I wait until I get close to an Apple store and have my machine looked at. It really is acting like it doesn't have enough RAM.
Before you do anything else, I suggest you either reinstall OS X or install a new copy on an external drive (such as a flash drive) and boot from that. If you still see the question marks, you'll know there's some kind of hardware problem. You can then experiment with removing one of the memory modules at a time.
OK, before I wrote this thread I reformatted my hard drive and reinstalled the OS. The only thing that the hard drive has on it currently is the OS and one profile. That did not help at all. I guess I can try installing a copy onto my external hard drive. How large of a flash drive would you need to run the OS from that?
That's enough to rule out software as the cause. The machine will have to be repaired. I can't tell you whether replacing the memory modules is what's needed.
Thanks so much for the feedback. I have talked to a couple of people who thought it may be the board, it also seemed to be getting quite hot on the top in the back. Perhaps the to issues could be related? It does not seem to be getting hot any longer, just running painfully slow. Hoping for a problem with memory unrelated to the board.
Hi. I experience the exact same problems with my iMac 2010 - I see the question marks after the memory in the "about my Mac" dialogue. And the machine works - except that it is extremely slow.
Did you ever manage to find a solution?
