Change (or restore) layerstate with lisp much faster than select from the ribbon dropdown list-why?

Hi.

changing layerstate from the ribbon dropdown list is very slow.

in a drawing (3D drawing, 391 MB) it takes about 8 sec to change layer state Via the drop down button,

and the same change done with lisp takes about 1.5 sec.

dose any one have an idea why?

thanks,

aridzv.
