What I have noticed with 2.6.6-rc1 on my dual G5 is that if I rsync a gigabyte or so of data over to another machine, it then takes several seconds to change focus from one window to another. I can see it slowly redraw the window title bars. It looks like the window manager is getting swapped/paged out.
This machine has 2.5GB of ram, so I really don't see why it would need to swap at all. There should be plenty of page cache pages that are clean and not in use by any process that could be discarded. It seems like as soon as there is any memory shortage at all it picks on the window manager and chucks out all its pages. :(
