<pre>Ah - so there are indeed several performance problems here; at least, when I
search for: multi_type_matrix in the sc/ library - I see 4.7bn perhaps up to
8bn pcycles in that code.
When I search for multi_type_vector I see 11bn pcycles (15%) as the top hit,
coming primarily from ScColumn::GetValue; but of course, I live to be mistake
=)
Pretty easy to no-op the ScColumn::GetValue method and see what the impact on
performance is I guess. Still - if it is easy to improve the matrix code it
would be worth doing.</pre>
