</div></div>The 2htdp libraries ("big bang") scale to a certain level of 'real world'. See the Realm of Racket book for some examples.<br>
<br>
If you need any performance, I recommend you start with the layer below 2htdp because you want to circumvent two inefficiencies in the current implementation: (1) big-bang and friends check a lot of things to catch errors very very early for students and (2) the functional approach is a bit too naive for hierarchical GUIs.<br>
