Slow response in Navision and SQL server

Hi all,

I have the following observation to share and I appreciate any feedback or sharing of information:

My client is running SQL Server option for Navision 3.6 on SQL server 2000. Users have observed that Navision is slow in response for the first time they accessed Navision for the day. They shared with me that it takes about 5 minutes for the Item Card to be displayed. Subsequent access to the Item Card is almost instantaneous.

I have found an article in MSDN. The URL is as follows:
http://msdn.microsoft.com/library/defau ... a_4azp.asp

In it, it describes the capabilitiy of SQL server to store execution plans & data buffers and the need to re-compile the execution plan when certain changes caused the existing plans to be invalidated.

My concern is if the SQL capabilities is related to users encounters and whether there are any work-around solutions.

Regards,
Spy
