Hi Roland,

I would suggest that it pretty much depends on the number of rows that are being returned from your select statement as well as the way the select statement has been put together.

Try cutting the select statement from the insert and running it against an explain plan to determine whether the select is optimised fully. Check to see whether the select statement is making use of available indices (if there are any) and consider trying various hint options to try and squeeze some more speed out of it.

Regards,
Kev.
