Some tips for low bandwidth OpenLayers usage. 1. singleTile, with a small ratio (~1.1 or so) will appoximate the behavior typical of most ArcIMS web interfaces -- single tile loading whenever the bounds don't match. or If you expect users to come back to the application a lot, tiled + long caching headeres may be better. 2. Build a single file build with minimal JS file for a small OL lib. http://docs.openlayers.org/library/deploying has more info. 3. Caching headers for pages and so on is useful. 4. mod_deflate can shrink your OL lib significantly. 5. Make sure your tiles are as small as possible -- I believe GeoServer (which I assume you're using) has support for 256 color paletted images, which are much smaller than full 32 bit pngs.
