I tried to load a larger (16000 datapoints) log into the map. bt747 becomes terribly unresponsive when displaying a large number of data points in the map. A solution might be to filter the dataset for heaps of data points in one location if there is not a simpler solution.

I guess that you labeled most of these datapoints as waypoints. I agree that in that case the application becomes unresponsive.
If they are only trackpoints, then the responsiveness should be great.
I should implement something to improve responsiveness regarding waypoint drawing and drawing them in a separate thread is maybe best - this thread could be pre-empted when there are updates to the map and/or for other activities. Grouping several waypoints into one (like in Google Earth for instance) is another way to improve responsiveness which surely requires more coding.
I put an entry in my todo list.
