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

Each chart bar shows, for one unidentified benchmark, how much the fastest PHP program used compared to the fastest Python 3 program.

(Memory use is only compared for tasks that require memory to be allocated.)


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 PHP programs faster? Approximately.

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

(Memory use is only compared for tasks that require memory to be allocated.)

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

 4 : Are there other PHP programs for these benchmarks?

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

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

 5 : Are there other faster programs for these benchmarks?

Remember - those are just the fastest PHP and Python 3 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.
