Hi,
Yes, for each mappoint component you drop on a form a mappoint.exe instance is started in background. mapooint.exe is in this case a COM server for your application. Each method is sent to it and returns with the appropriate data.
Of course this gives delays, and if you wants to drop honderds or more pushpins on your map you will have incredible delays. But these delays are not nececarly because the delay of interprocess.
For a large amount of data is nececarly to study (or better trial and error) to see what the most gain gives in speed. Not very easy all the time
