Fuzzy Logic Performance

Hello,
I am just wondering if someone out there has tried some Fuzzy matching on databases of large scale i.e - about 20 million contact records. Suppose I wanted to perform matching/ grouping to 10 000 incoming messages. How fast does this usually take? What is the dependence on the number of fields chosen for the match?

Any insight is greatly appreciated,

Lubomir
