I have windows mobile application that display information from an sql server ce. Normally takes about 6 sec to load a grid of 6 rows.
Recently I realized that if I open the db on the mobile using the query analyzer tool, and then run my app everything runs about 5 times faster, then I close the query analyzer and continue using the app and everything slows down.
Did someone knows why this happens, and how can I get this performance without asking the user to open the query analyzer tool first?
Open a database connection at application startup and keep it open for the lifttime of the application. (Do not use this connection object for anything)
