Question: Why do I have very slow inserts of numerous records using Firebird (I have several hundred thousands of records)?
Answer: Please donít use TpFIBDataset, because this is a buffered dataset. You will also have memory problems with TpFIBDataset. Use pFIBQuery with parameterized inserts instead. A commit after 500 should be ok. We made a text-import component and are able to put 100.000 records in 4 seconds with this approach.
Tips:
  • Try set : TpFibDataset.Unidirectional:=true; before open.
  • Try Use TpFibQuery
  • If on local PC use the local connection

What a good job you did! Keep coding great pieces of fast and efficient software:) We started using FIBPlus back in 2001. Since then, every project we offer uses FIBPlus to connect to FirebirdSQL. You library has always been stable, flexible and rocket fast ! Our major project, an helpdesk/data mining application, concurrently used daily by more that a hundred technicians and analysts, uses FIBPlus. Now that FirebirdSQL 2.0 is available, we have been able to upgrade our application quickly and painlessly - that's another reason you can be proud of your work ! >>
