I've got a iMac with 8gb installed, a core 3.1GHz i7 processor.
There are 2 areas where the system is running ridiculously slow, when I start any app. The computer doesn't respond at all for 30 seconds+.
I've just timed the startup of Lexar's Image Rescue 4 program. From clicking it's icon in the dock it took 50 seconds before the icon started bouncing, 56 seconds for the app's flash window to appear and 1 minute for the main window to appear.
The other speed issue I have is open and save dialogs. Click Documents, for example, the gear wheel spins for nearly a minute before the folder's contents is displayed.
Once the programs have started they run fine, no problem. Once Documents contents have been displayed everything runs smoothly (unless you click to a lower level folder in which case that will be slow).
I can't guarantee it, but I think this all started with the last system upgrade, to 10.9.1 which I installed on 17 December.
Anyone else getting this problem?
