slow sql server DB reads

[Larry Bates]

If GUID is not a key in the database make it one.  That
way you won't have to do serial reads through the entire
table to locate matching entries.

It is hard to be more specific because we don't know how
many records are in ASPSessionState table.  If there are
only a few, the problem is probably elsewhere.  If there
are many, indexing on GUID would provide speed improvement.
