There should be zero performance difference if I'm not mistaken.  raco
exe just bundles a copy of the Racket executable along with the
transitive closure of the bytecode used by the program and its
dependencies.  As the first paragraph of
http://docs.racket-lang.org/raco/exe.html says, "Running an executable
produced by raco exe will not improve performance over raco make."
