is it a single record insert or an insert select? how many indices do you have on the table? have you run a trace and looked at the duration column for the steps in the process? Do you want to post your code?
If one brings so much courage to this world the world has to kill them or break them, so of course it kills them. The world breaks every one and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry. Earnest Hemingway, A Farewell To Arms.
