Any idea why the cost is so high?
On Windows, we do the expensive security check when you open a handle (aka fd) and you are granted tbe desired rights until you close the handle. There is a cost when using handles of checking that the handle has been given the right needed for each operation, but it's a single AND and a comparison that happens in the handle table lookup codepath.
What does SELinux do that is more expensive?
