I also use 8765 knowing only that it fixes the issue of a field returning the wrong data length in ODBC. I would love to know if it effects perfomance of other queries run while it is on.

This is great!
I really don't like M$ attitude about trace Flags. Why do we have to go through so much trouble to know (and compile) these things?

Trace flag 8030 for SQL 2005

http://support.microsoft.com/kb/917035
FIX: Query performance may decrease after SQL Server 2005 has been running for a while

Symptoms
Consider the following scenario. A server has been running for a while. Then, you run a query in Microsoft SQL Server 2005. In this scenario, the query performance may be slow.
<...>
This problem occurs only on 64-bit servers that have more than 16 gigabytes (GB) of physical memory.

Resolution
You do not have to restart the computer after you apply this hotfix. However, after you apply this hotfix, you must add the -T8030 option as a SQL Server startup parameter to enable trace flag 8030. Then, you must restart the SQL Server service for the hotfix to take effect.
