OK I found the cause, it was a default settings added on server start.
(-B 1024) Grrrrrrrrr!!!!!
Now it works really better I devide the full time per 2.
I suppose I steal have to look deep in the procedure to see some hack,
has somebody suggest, I will try to buffer all updates in one.
One question, Could I optimise the treatment if I'm doing the select on
a view while updating the main table ????
regards
David
