I use iMac 2009, 2.93 GHz Inter Core i7, 8GB RAM, 1TB HD. The file has many artboards. There's 56 artbord. The artbords are 960x640 pixel, RGB, 72ppi.
I experience a slow performance working on a 87mb AI file. And I get a weird bounding box (not always) when I select anything. this photo explains the case:
The selection is at the left as you see. The bounding box reaches the last artbord at the right which has no elements at all. Even if I don't drag my mouse to select elements, and just click once on an object, this bounding box appears as if I am selecting some other object in the same time that is far from my selection which creates a big bounding box.
Also, When I copy elements from one artbord, and go to another and then hit cmd+f (which should paste the object in the same place in the new artbord that's selected same as it was in the arbord that was copied from) it doesn't always paste it in that artbord, sometimes I find out that it pastes in another artbord that i didnt select. sometimes it works right sometimes it doesnt.
I opened a new file with less artbords but the same settings, but the program is still slow and takes time for every move I make.
I must mention that I am recently having some issues with OSX Mountain Lion, such *** a laggy animations in the operating system itself for example when I enter full screen in safari. It should expand the safari window and slide to the right where it opens in a new desktop, but what actually happens is that it doesn't move in an animated mode, it becomes big suddenly and the slide animation doesnt happen. I don't know if any of this has to do with the lagg of the program.
I'd appreciate any help with this, thanks a lot in advance.
