Tips for speeding up Pro Maps
Reduce the number of pins/properties showing at once.
We think the map works best showing < 100 pins/properties at once. That means you'll want to filter the map in most cases. And in some cases you may to prevent the map from rendering at all unless it's filtered. Notes on how to do that at the end of the page here.
Use smaller images in popovers.
Consider using FileMaker's GetThumbnail() function to make the images you use in your popovers as small as possible.
Don't show images in Popovers when on the WAN.
The "Load Thumbnails" script (which is set to run at startup as a subscript of "Initialize ProMaps") exports all of the images used in popovers to the user's temporary directory. This can be VERY slow especially if the images are large (see thumbnails above). You may want to make the execution of that "Load Thumbnails" subscript conditional based on the user's connection type.
