Has nothing to do with window speed or anything of the sort.

 

Spraying the window slide channels with silicon spray will greatly improve the action of the windows. It is clean in use will not mark clothes and is safe around food preparation areas. Give it a go you can also use it on door seals (stops rubber squeaks) and also on plastics.
