Question:
Why do I have very slow inserts of
numerous records using Firebird (I have several hundred thousands of
records)?
Answer:
Please don’t 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
I've looked at FIBPlus and feel that it is one of the fastest (if not the fastest) IB components out there. Congratulations on doing such a fine job. >>Barry McClure
