Hello Ben,

The comparasions probably are available somewhere, but tracking the
down may prove difficult. Since the functions are CPU intensive yo
want threads that are aren't very far removed from machine code. A
object oriented langauge like C++ offers that capability. The downsid
is the creating objects that comply with the Component Object Mode
(COM). COM has over 200 built-in interfaces. Unless you are ver
familiar with constructing COM objects, don't attempt this as a firs
time project. A XLL would be easier to create and the speed tradeof
can be kept to a marginal level. C# would be a good choice if th
workbook were to be web based, but would still be slow even if i
isn't.

Sincerely,
Leith Ros
