In my experience, Opera, Firefox and Safari are good enough for web-
mapping applications. You can see one example at http://www.carto.net/
williams/yosemite/ - which probably has similar filesizes like yours
or even bigger.
Firefox2 is rather slow, but Firefox 3 is much better. Safari is
quite promising, esp. with bigger files. Opera has good performance
and is the most complete SVG implementation, but it can be a little
slow for bigger files (>30000 elements in the DOM) but its improving
from version to version.
Of course there are lots of places for performance improvements. For
map data I also recommend trying to reduce the number of elements in
the DOM (within the GIS) and gzipping (on the fly) on the map-server.
See section "Ideas to improve performance" at the bottom of the web-
The Intergraph solution might not be as flexible as the Postgis/PHP
solution described, but some ideas might help with Intergraph as well.
