The DAT Query and DAT Filter are powerful and flexible features.  Depending on the complexity of the query and the amount of data it may take some time to process the request.  Even if the query looks simple, some of the tables are performing advanced calculations to make the data more convenient for you to work with.  The more tables, conditions, and filters included in a DAT Query the slower it may become.

Some suggestions to improve the speed of your DAT Query or DAT Filter:
- Instead of using Contains, Not Contains, Starts With, or Ends With, use the “=” or “<>” DAT Operators.
- Avoid relinking to the same table multiple times.
