Hi Sparky,

Have you run the SP in the Query Analyzer. If so, is there any performance issue?

Based on my experience, the issue seems to be an ODBC performance issue executing the pass-thru
query from MS Access. The issue can be caused by the Page Latches when perform the insertions. Please
read the following articles to exclude some known issues and apply the suggestions within the following KB
articles:

209091 ACC2000: How to Optimize Microsoft Access When Using ODBC Data Sources
http://support.microsoft.com/?id=209091

208858 ACC2000: Optimizing for Client/Server Performance
http://support.microsoft.com/?id=208858

If the verion of Jet engine 4.0 is earlier than 6.0, I recommend you apply the latest Jet 4.0 SP8 via:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;829558

to suppress the performance issue described in the KB 302496:

302496 ACC2000: Queries Are Slower After You Install Microsoft Jet 4.0 Service
http://support.microsoft.com/?id=302496

Please apply my suggestions above and let me know if this helps improve the performance. If there is any
headway from you, or should you have any questions and concerns on the , please feel free to post it in the
group.

Regards,
