I was wondering if there is any trick I can use to speed up zooming in/ out or panning through my maps in Arcmap. I usually work on county-wide studies in which I have lots of base layers, imagery and annotation which slow me down very much. I try to keep unnecessary layers off but can't think of anything else. I am using ArcGIS Desktop so I suppose I can not use caches. I have not tried it yet but I guess I can use Dice (Data Management) to increase my speed. Any thought/ comment?
I think you should investigate Basemap Layers:
Basemap layers are a kind of map layer that provides a framework onto which you display your dynamic operational information. Basemap display performance is very fast. Since basemap layers are relatively static and do not change frequently, their display can be computed once and reused many times. The first time you visit an area at a particular map scale, basemap layer display is computed. The display is recalled on return visits to that area and map scale.
