This is another common mistake made by new users and what annoys me so much about theses low spec machines that can't reach correct feeds for what they are advertised to do.
The feeds are really dictated by the material and cutter your using not your preference or desire to be in rush or not. Also 3D work (dispite what you see there's really only 2D or 3D) often means high feeds rates or/and fast acceleration because of the small moves with light DOC or tiny step over amounts.

Cutting slower just costs you more money because of excess tool wear and leaves poorer finish. It also as you say cost's more in electricty and time.
