 1 : Are the Perl programs faster? At a glance.

Each chart bar shows, for one unidentified benchmark, how much the fastest Perl program used compared to the fastest Python 3 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 Perl programs faster? Approximately.

Each table row shows, for one named benchmark, how much the fastest Perl program used compared to the fastest Python 3 program.

Perl used what fraction? used how many times more?

 3 : Are the Perl 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 Perl program are shown for comparison against measurements of the fastest Python 3 program.

 4 : Are there other Perl programs for these benchmarks?

Remember - those are just the fastest Perl and Python 3 programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Perl.

Maybe one of those other Perl programs is fastest on a different OS/machine.
