I don't think one performs any faster than another. But, it is considered Best Practice to not name your Stored Procs as sp_*.

>Performance was exactly what I was worried about. If I understand it correctly it should be slightly faster for the server to execute a SP named usp_X compared to a SP named sp_X since the server doesn't first have to check if it is a system SP. (now slightly faster might only be a fraction of a fraction of a ms faster but still).
