The Euler Benchmark Suite aims at comparing language speeds for the Euler Project Problems at http://projecteuler.net/.
This currently consists of Perl 5, Rakudo Perl 6 and Parrot solutions, but all languages are welcome.
In order for the included comparison scripts to work, you need to ensure that you have the necessary dependencies installed.
cd into the git checkout
cd euler_bench
perl Makefile.PL # answer yes to installing deps if you want comparison scripts to work
make installdeps
Or if you have cpanminus (you should), then just type:
cpanm --installdeps .
Files in each directory are named according to:
<language>/<3-digit project euler number>/<2-digit implementation number>.ext
