In my arch Linux chroot environment on my nexus 4 a hello world program in
racket/base runs in .37 seconds, and strace reports 95% of time spent in read.
So I bet you'll get something in that ballpark after

Here’s the result of `strace -c -f -- racket -l racket/base` for Racket 6.1.1.8

Set the environment variable PLTSTDERR=debug to get more verbose output.

could use strace to find the latency on different system calls made duri
