I'm testing the exchange partition and it's taking 90 seconds to exchange a table containing 700 000 rows with a partition containing also 700 000 rows.

I've noticed that SYS is doing a crazy select to check on the PK of the tables even if I used whitout validation in the exchange statement.

I this normal behavior ?
