1 : Are the Racket programs faster? At a glance.
Each chart bar shows, for one unidentified benchmark, how much the fastest Racket program used compared to the fastest Lisp SBCL program.
These are not the only compilers and interpreters. These are not the only programs that could be written. These are not the only tasks that could be solved. These are just 10 tiny examples.
2 : Are the Racket programs faster? Approximately.
Each table row shows, for one named benchmark, how much the fastest Racket program used compared to the fastest Lisp SBCL program.

3 : Are the Racket programs faster? Measurements.
These are not the only tasks that could be solved. These are just 10 tiny examples. These are not the only compilers and interpreters. These are not the only programs that could be written.
For each named benchmark, measurements of the fastest Racket program are shown for comparison against measurements of the fastest Lisp SBCL program.

4 : Are there other Racket programs for these benchmarks?
Remember - those are just the fastest Racket and Lisp SBCL programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Racket.
Maybe one of those other Racket programs is fastest on a different OS/machine.
