Aperture slowing down on 2.66Ghz iMac

I think it might be the largely the SSD making the Air faster. If 4GB of RAM is not enough for aperture it will start using the SSD/HDD as scratch disk space/virtual memory. If it does this, the SSD with be much faster than the hard disk. It's likely it's paging out on both machines but the SSD makes it less noticeable. Of course if you can increase the memory so that it is not using scratch disk as much in the first place the results will be much better. If it's only about $50 to upgrade the RAM, I'd consider that low hanging fruit. Running a program like Onyx can clear up some system logs and caches and run basic disk and permissions checks that could speed somethings up.

I haven't had any issues with Onyx but always recommend backing up a system before running any program like this or a defragger just incase something goes wrong.
