Nudging very slow in CS6

Question

hello --
i have seen quite a few threads but no solutions yet that work for this problem. my documents tend to have quite a few of layers, using very frequently shapes with layer effects. up to a certain amount of those the app is very responsive, and then once i hit a certain level it gets very slow. strange just moving a vector shape using the direct selection tool is just fine. the regular nudging of a group or a layer brings up the progress indicator dialog.
so far i have tried:
- turn off layer previews (did improve things a tiny bit, but still unusuable with larger layer count)
- changed performance settings (cache level:2 or 4, and tile size 128k) (also no effect)
the only thing that seems to help is to break the file apart into seveal ones, which will have less layers, but that's not really a long-term workable solution for me, as i use layer comps and need a more global overview.
have others found a solution? i can't imagine being the only one with this problem.
thanks in advance for your throughts.

It doesn't sound too terribly large, though 300 MB isn't small.  Do you know whether you have information beyond the visible edge of the canvas (e.g., have you used the Crop Tool with [  ] Delete Cropped Pixels unchecked, or placed any large images of which you can see only a portion?
I only have an intuitive feel for this issue, as I frequent this forum and have read a number of other reports of sluggishness, but I don't have a Mac on which to test things myself. 
There have been some reports that 13.0.1 makes things better, but it still seems there is something that pushes people's Mac systems over the edge into being sluggish, and unfortunately Adobe or other users haven't managed to find a magic bullet.
I've heard folks say everything from running Onyx to reinstalling the entire operating system has helped, but that's second hand info as I just don't have the ability to duplicate your environment.
There was a thread where someone posted a document with a huge number of layers to test with, and another where someone suggested documents of a certain composition, and it was pretty easy to demonstrate that some systems could work through them more quickly than others, with the difference being greater than you'd expect based on computer performance alone.
If you have a way to post your PSD file online and would be willing to show it to others, I'll be more than happy to download it and see whether I'm seeing similar performance.  A document that can reproduce a slow-down for others might be very interesting to Adobe as well.
