What does the execution plan look like? Just curious.

There is way too much information missing here. What is the point of @Date? It isn't in your query at all. Why is @Date a varchar and not a date/datetime? What is the point of using CROSS APPLY here? Those are simply a computed column. To really help we would need an execution plan (estimated is probably all you can get), table definitions including indexes. I am guessing you need some indexing here but without a lot more details it is guess work.
