One piece of advice, pay the outrageous price to get a SQL Server "expert" to review your needs, specify hardware and help you install. You can do it all yourself but there are lots of tricks and poorly-documented tweaks that can make an unbelievable difference.

>Summary: in my experience SQL Server is as fast or faster, as you would expect from a server-based system where I'll bet the server hardware is much better than that you used for VFP.
