I've noticed that the time it takes to enter my ListActivity is fairly
proportional to the number of items in the sqlite cursor.   Indeed,
when I look at a trace, it seems as though fillWindow (i.e. filling
the cursor window) takes a HUGE amount of time when working with a
large cursor (one with thousands of rows).

Does Android really load every single row into memory?   How else to
explain literally seconds of time (not debugging) entering a list of
2000 items (the time in fillWindow is minimal with a smaller list;
again, roughly proportional).

Can anyone with an understanding of the internals help me out here?

Thanks.

Marc
