I am experiencing a slow performance while one user is connected to the
database and when the second user connects and try to perform some commands
like (Dcount, DSum…, or run any SQL statement…) it will take almost 15
double of the actual time with no other user is connected??

The three most common performance problems in Access 2000 or newer
a
- LDB locking which a persistent recordset connection or an always
open bound form corrects (multiple users)
- sub datasheet Name property set to [Auto] should be [None]
- Track name AutoCorrect should be off

If the problem is for everyone when starting up the MDB then it likely
needs a decompile.

For more information on these, less likely causes, other tips and
