Richard,

That works out to 277 rows per second.

That not terrible, but I have seen better.


Are there any triggers firing for the inserts?

How big is an average rows? How many fields?

Well your on the right track, indexing can make things real slow.

How often are you committing the rows?

The only thing that FB2 has changed which would affect insert
performance, is the new ODS structure for the indexing data, which would
make the process slightly slower as the structure has more pages to
update.

(This slow down on inserts pays significant dividends later on SELECT
statements, which can run much faster due to the new structure)
