 1 : Are the Python 3 programs faster? At a glance.

Each chart bar shows, for one unidentified benchmark, how much the fastest Python 3 program used compared to the fastest Java 7 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 Python 3 programs faster? Approximately.

Each table row shows, for one named benchmark, how much the fastest Python 3 program used compared to the fastest Java 7 program.

Python 3 used what fraction? used how many times more?
Benchmark	Time	Memory	Code
pidigits †	1/2	1/9	1/7
regex-dna	±	1/3	1/2
reverse-complement †	4×	2×	1/5
k-nucleotide	12×	±	1/2
binary-trees	15×	±	1/2
n-body	45×	1/3	±

fannkuch-redux	61×	2×	1/2
mandelbrot	64×	1/10	±
spectral-norm	64×	2×	1/2

Python 3 used what fraction? used how many times more?

† possible mismatch - one-core program compared to multi-core program.

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

 3 : Are the Python 3 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 Python 3 program are shown for comparison against measurements of the fastest Java 7 program.

 4 : Are there other Python 3 programs for these benchmarks?

Remember - those are just the fastest Python 3 and Java 7 programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Python 3.

Maybe one of those other Python 3 programs is fastest on a different OS/machine.
