If you run your application on a WAN, you need to be more considerate
with your design. Make sure you don't return unneeded columns in your
result set (no SELECT *!). Also make sure that you don't have a lot of
extra network roundtrips. If you need to find data for ten orders, run
one query not ten.

varchar data, I assume. Query text is sent as Unicode. Parameter values
in RPC calls are sent in their native format. So nvarchar will be Unicode,
varchar will be 8-bit chars, and an integer will be 4 bytes.
