Here's a guess on the speed difference.
It really depends on when the stored procedure is compiled.
When astored procedure is compiled, a query plan is created
based on the distribution of the data and the indices that were
available at that point in time.
So it is possible for a simple select statement to be faster than a
stored procedure if the stored procedure is using stale information.
The way you do your benchmarks can significantly affect the timings
also. Can you share your benchmarks with us?
