I found that adding and querying slowed right down when the number of records approached 10000. The records I was using included string fields. It was probably quicker with just numeric fields. And clientdatasets may have improved since then. However, the performance was not good enough for me, and I went with an embedded firebird DB instead. cheers, Chris
