Step 1 : Are the Python CPython programs faster? At a glance.
This chart shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.
Each chart bar shows, for one unidentified benchmark, how much the fastest Python CPython program used compared to the fastest PHP program.
Step 2 : Are the Python CPython programs faster? Approximately.
This table shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.
Each table row shows, for one named benchmark, how much the fastest Python CPython program used compared to the fastest PHP program.

Step 4 : Are there other Python CPython programs for these benchmarks?
Remember - those are just the fastest Python CPython and PHP programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Python CPython.
Maybe one of those other Python CPython programs is fastest on a different OS/machine.
Step 5 : Are there other faster programs for these benchmarks?
Remember - those are just the fastest Python CPython and PHP programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
Maybe one of those other programs is fastest on a different OS/machine.
