No, I doubt that it would as all the time is probably being taken up inside
the Windows DLL code rather than in your application. I'll see what I can do
to optimise loading items in the next release (or two).

The number of items is really only limited by memory, but of course the more
you "load" in to the ListView the slower it will be. A "virtual" listview
simulates loading heaps of data but in fact only loads what would be visible
at any one time. Yes, it is not easy 'cos you have to handle scrolling
etc...
Another idea, if loading time is the issue, why don't you see if hiding the
listview during loading (maybe a "please wait..." message) and showing it
when all is loaded. This might speed it up a bit if it's not doing all the
graphics during the load.
