I have a MBP with 8gb ram, and an 27" i7 iMac, with 16gb of ram, and a 512 SSD. When Im swiping through pages on the MPBs trackpad, or swiping up, down, to show desktop, etc., everything works smoothly, but on my iMac, which is a more powerful machine, Im getting lag. The only time I dont get these issues on my iMac is when I restart it, but after a while, I get the lag. I get the lag on both the wireless trackpad, and when I press one of the shortcuts on my Logitech mouse. Im not running anything that takes up a lot of power from the iMac, with chrome, firefox, and itunes being the main programs open.

For example, I will swipe to the right to take me to another window on my iMac, and there will be a 2-3 second delay before it actually switches. Or when I press one of the buttons on my Logitech mouse, to show me desktop for example, it has the same delay. Even if I press the shortcut keys on the keyboard, I get the same response. Anyone have any ideas as to what is going on?

Please provide the models and software versions of these machines. Are there any Logitech drivers loaded?

I assume you are running Mavericks on everything with Logitech drivers on the iMac. You don't mention SSD for the MBP but you do mention it for the iMac. Do you have TRIM enabled on the iMac?

Mavericks on both.

Logitech drivers on the iMac. I use a bluetooth Logitech mouse with the MBP from time to time.

And TRIM is enabled on both.

I remember that I had a code that I use to paste into Terminal for the iMac, which would make it run smoother for a while, but it would give me the pauses afterwards.

I have an SSD on the MBP, with a 2nd HD in the optical bay. I have the same setup on the iMac, with the SSD in the optical bay, which runs the OS.
