I am working on a little project to remotely drive a VR headset with code 
written in Racket as an attempt to make a significantly faster development 
environment for certain types of VR apps.  I am worried about what appears to 
be the compile speed.

It takes over three seconds from hitting ctrl-R in DrRacket to executing the 
first statement of a 350 line typed racket program.  It only uses:
#lang typed/racket/base
(require racket/tcp)

That seems to be about twice as slow as a larger untyped racket program using a 
bunch more stuff, but even that isn't great:
#lang racket
(require 2htdp/universe)
(require 2htdp/image)
(require 2htdp/planetcute)
(require (only-in racket/gui/base play-sound))

Does Run from DrRacket  have a significant time penalty?
Are there any steps I can take to make typed racket compile faster?
In many cases I don't care much about the execution speed.

I would like to think that compiling and running a few hundred lines of code on 
a modern desktop system should be essentially instant.
