Python CPython ÷ Perl | Computer Language Benchmarks Game

Step 1 : Are the Python CPython programs faster? At a glance.

This chart shows 3 comparisons - Time-used, Memory-used and Code-used.

Each chart bar shows, for one unidentified benchmark, how much the fastest Python CPython program used compared to the fastest Perl program.

Step 2 : Are the Python CPython programs faster? Approximately.

This table shows 3 comparisons - Time-used, Memory-used and Code-used.

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

Python CPython used what fraction? used how many times more?

± read the measurements and then read the program source code.

Step 3 : Are the Python CPython programs faster? Measurements.

This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ~ CPU Load.

For each named benchmark, measurements of the fastest Python CPython program are shown for comparison against measurements of the fastest Perl program.
