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

Each chart bar shows, for one unidentified benchmark, how much the fastest Cython program used compared to the fastest Numba 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 Cython programs faster? Approximately.

Each table row shows, for one named benchmark, how much the fastest Cython program used compared to the fastest Numba program.

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

Cython used what fraction? used how many times more?
Benchmark	Time	Memory	Code
iobench †	1/257		±
n-body †	1/5		±
fib50 †	1/3		±
templates †	1/3		±

Cython used what fraction? used how many times more?
Time-used	|-	|---	25%	median	75%	---|	-|
(Elapsed secs)	1/257	1/257	1/10	1/4	1/3	1/3	1/3

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

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

 3 : Are the Cython 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 Cython program are shown for comparison against measurements of the fastest Numba program.

 4 : Are there other Cython programs for these benchmarks?

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

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

 5 : Are there other faster programs for these benchmarks?

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