Hello, we are trying to improve the performance of MapXtreme Java. From the
MapInfo Products Knowledge Base, performance tuning (

I am looking at the following suggestion:
Set appropriate coordinate system type for the task: To optimize image
rendering, set the display coordinate system to the one that is used by most
of the layer data. To optimize raw data access, set the numeric coordinate
system to the coordinate system that most of the layer data is in. The
numeric coordinate system is used for all numerical data associated with
MapJ, such as the bounds, zoom, and center.
For our map, we have entire US coverage. We are using Latitude/Longitude
NAD83, Unprojected for both the display and numeric coordinate systems.
Does this seem best? Does anyone have any recommendations regarding the
coordinate system/projection used?
Thanks in advance,
Kristi.
