I did a write-up in the Gist listed below, but the result seems to be that even functions that run Racket only code with no IO or calls into C libraries run slower in Racket CS. Code that calls into the database library to run SQL insert queries runs significantly slower. The only things which were faster in Racket CS were one "Racket only" function, `df-histogram` and a function which retrieved data from an SQL query, `df-read/sql`
