My illustrator seems to be taking naps, that blue wheel turning and churning ;( Damn blue circular thinking and greye'd out .ai window focus. 

My art is a polygon design with anywhere from 500 - 1000 triangle paths, sometimes that is doubled as my designer duplicates the layer to fix this one line pixel liner issue....BUT its sometimes taking anywhere from 3min to 10 min to just resize the image or copy and paste it onto a new layer or new document.

What am I or my computer doing wrong? 

Is this commonplace with Creative Cloud 2015 ? or is it a scratch disk issue / or Graphics Card GPU performance setting issue?

Should I be using outline mode when redrawing objects? or should I Try to group these 500 triangles into one graphic & then resize [ granted I'm not going to need to redraw or tweak any of the polygons]? 

Much thanks guys / gals ;))
