We have a fairly high-traffic ACF 8 site where SQL Server database gets hit
with two types of queries:

type 1 - about 1-5 SELECTS per second that have to run as fast as possible
*always* (< 1 second)
type 2 - about 100-500 "other" queries per day that are allowed to run
"slower" (5-20 seconds). (These are reports, automated processes, etc.)

I know I can declare "SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED" on
some of those type 2 queries so that they do not issue locks on tables that
type 1 requires to do its thing.

My question is: if the goal is to make sure type 1 remains as fast as
possible, will it help/hurt to also declare "SET TRANSACTION ISOLATION LEVEL
READ UNCOMMITTED" on type 1 queries?
