      The reason is that checksums will have to be calculated for every 200.000 rows uing every columns if you do not use the and optimization parameters. You have noticed that first INSERTS, next UPDATES and finally DELETES are done. To check for UPDATES checksums are needed.


      @Manoj      : why will updates have to wait for checksum to be built? Does DELETES use the checksums?
