Fastest Look At?

Is there a way to do this faster?

llLookAt(position, .1, .01);

Do you mean so that it turns instantaneously, rather than where you can see the motion?

As far as the visual effect goes, not reliably. The viewer seems to almost always interpolate motion when translating/rotating. However, as far as the simulation goes, llSetRot is instantaneous (though it will only work on non-phys). It will still appear to turn slow enough for you to see it, and any client-side effects will still be affected by the movement (particles will spray in a fan, for example). The only way to stop that effect is to turn off velocity interpolation of objects in the Advanced menu. However, that only affects your view of it, not the appearance for everyone else.

There is no way to reliably do instantaneous move/turn (that I know of, anyway).

yeah it is physical.
