[mapguide-users] Is there a file size limit?

Wed Aug 27 13:30:13 EDT 2008

No we are not using any filters.   There is a single layer for wetlands, 
lakes,  rivers, double line rivers, and waterbodies and land.  Single line
rivers is the largest layer in the map group.   We have increased the cache
size and now it is better but  still chokes at large scales beyond 1:10,000
for some reason.  thanks
