When you say "hesitates" do you mean that the FROM or TO clips freeze momentarily?
If this is a fade with a long duration, expect that behavior on a crossfade. Use either an overlap fade (which will change the duration of the clips slightly) or MODIFY each clip, using the OPACITY keyframe settings to fade one clip down and other up.
