R7RS Benchmarks

Benchmarks for various Scheme implementations. Taken with kind permission from the Larceny project, based on the Gabriel and Gambit benchmarks.

See the results here

Running the tests

Just run

./bench <scheme> <test>

Schemes that should work:

• Bigloo (bigloo)
• Bones (bones)
• Chez (chez)
• Chibi (chibi)
• Chicken (chicken)
• Cyclone (cyclone)
• Foment (foment)
• GambitC (gambitc)
• Gauche (gauche)
• Guile (guile)
• IronScheme (ironscheme)
• Kawa (kawa)
• Larceny (larceny)
• Loko (loko)
• MIT/GNU Scheme (mit)
• Mosh (mosh)
• Petite Chez (chez)
• Picrin (picrin)
• Racket (racket)
• Rhizome/Pi (rhizome)
• RScheme (rscheme)
• Sagittarius (sagittarius)
• Scheme48 (scheme48)
• Scheme 9 from Empty Space (s9fes)
• TR7, tiny R7RS interpreter (TR7)
• Vicare (vicare)
• Ypsilon (ypsilon)

This should result in a file ./results.<scheme>.

All of these Schemes are packaged for ArchLinux. The tests are run with whatever that package produces.

Run

make csv

to produce a file all.csv with the test results (<scheme>,<test>,<seconds>).

Limiting compile-time and run-time

The environment variable CPU_TIME can be set, to limit the time for compilation and for running (each individually).

CPU_TIME=3600 ./bench chez all

Path to executables

You can set an environment variable to specify the path to each Scheme.

LARCENY=/tmp/larceny/larceny MIT=/tmp/mit/mit-scheme ./bench "mit larceny" "fib ack"

Notes for specific implementations

Chicken

The chicken test code assumes the presence of

• vector-lib
• r7rs

Install them by running

chicken-install vector-lib r7rs

Racket

The racket test code assumes the presence of https://github.com/lexi-lambda/racket-r7rs.git.

Install the r7rs package installation-wide.

Run:

sudo raco pkg install --scope installation r7rs

IronScheme

Install the latest version of .NET Runtime (currently 9.0-preview, requires at least IronScheme 1.0.357) from https://dotnet.microsoft.com/en-us/download/dotnet .

The default binary for IronScheme (can be changed by exporting IRONSCHEME in your shell before running bench) is called ironscheme.

If you unpack IronScheme in your home, you can create a shell script like the following:

#!/bin/bash
export DOTNET_CLI_TELEMETRY_OPTOUT=1
dotnet ~/IronScheme/IronScheme.ConsoleCore.dll $*

and put that somewhere in your $PATH.

Stalin

Before calling Stalin, the code is run through alexpander (by default using Chicken’s csi). Then stalin is invoked on the result.

Unsupported Schemes

Owl Lisp

Missing a lot of necessary functions, read for example.

TinyScheme

Problems with redirecting input, read chokes. No timing functions.

Safety

The benchmarking code does not use unsafe optimizations. These make code run even faster (but less safe ;) Specific options that could be used are:

Chez

--optimize-level 3

Gerbil / Gambit

(declare (not safe))
