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

Each chart bar shows, for one unidentified benchmark, how much the fastest Pyston 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 Pyston programs faster? Approximately.

Each table row shows, for one named benchmark, how much the fastest Pyston 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 Pyston 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 Pyston program are shown for comparison against measurements of the fastest Python 3 program.

 4 : Are there other Pyston programs for these benchmarks?

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

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

 5 : Are there other faster programs for these benchmarks?

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