Windows 7 SP1 x86, ODBC, and SQL Native Client Performance


  • Good Morning Everyone,

    Since applying SP1 to select Windows 7 Ent machines (testing before mass install), I have found that one of our applications that uses the SQL Native Client for an ODBC connection is awfully slow. It takes 5 minutes for the application to load and come back with initial data load/presentation. I have tried every other SQLCLI install available, including 2005, 2008, and 2008 R2. This was the case when I first tested the application with Windows 7 about 6 months ago until I found driver version 2007.100.2531.0 SQL Server Native Client 10.0, which seemed to resolve the slowness issue. Now, after applying SP1, it has reverted in being slow.

    Is there anything I can look for or modify that might be causing this issue? What part of SP1 touched the ODBC or SQL driver?
