Also have you verified that the slow performance is due to the virtual
function call? In general, this is not an area that you can target and
expect to get big gains. You said that your program is 'very slow'.
If you want to speed it up by an order of magnitude, you probably won't
be in luck just attacking the virtual function call,
Paul.
