Excel 2007: Making Excel better with UDF's

I inherited a bunch of workbooks that each contain over 60 sheets, each  containing over 100 thousand Index/Match formulas. It runs pretty slow...

The owner wants to increase performance, but loves his formulas that update on the fly. I was thinking, if I could give him a User Defined Function that runs faster than Index/Match, that would get him part of the way there. Is this possible? If so what would be the process/VBA code?

It would be pretty cool if we could create UDF's that are more efficient than what Excel provides.
