Trudy, raising priority of this bug to P1. The regression is regarded to be critical (after discussion with Monty). Still left the bug to open to have accurate benchmark information.

Note that this regression happened two years ago (December 2004)

Is grant_options only an optimization that allows code to avoid checks for grants when there are none? My servers always have grants. I want to fix the original bug (24988) without taking the performance hit. Do I get that by never settting grant_options to FALSE?

The bug is not planned to be fixed in 5.1 or 6.0.

The performance regression was only according to Monty. Was never verified by our benchmarking or reported by a user. Maybe there is no noticeable regression whatsoever. I have no interest in looking at this bug unless there is evidence that the regression is real.
