I'm hoping someone is still looking at this post. I have implemented the algorithm and it is working just fine. However, it performs quite horribly with my table with 60k rows. Is there anything I can do to speed things up? my table has basically first name and last name and that't it.

running a query as such

select [dbo].[JaroWinkler]('smith', LAST_NAME ) from LEIE could take up to 7 minutes.

Any Idea would be most appreciative.

Thanks!
