Are the Python CPython programs faster?
Do the Python CPython programs use optimized assembly code libraries? Are they small simple programs or very optimized programs? Do the Python CPython programs use a fraction of the time used by other programs or do they use several times more?
| Python CPython used what fraction? used how many times more? | ||||
|---|---|---|---|---|
| Programs | Time | Memory | Code | Reduced N |
| ↓ reverse-complement | ± | 3× | 1/3 | |
| ↓ k-nucleotide | ± | 2× | 1/4 | |
| ↓ binary-trees | 6× | 10× | ± | |
| ↓ mandelbrot | 14× | 1/2 | ± | |
| ↓ fasta | 23× | 7× | ± | |
| ↓ n-body | 63× | 7× | ± | |
| ↓ spectral-norm | 74× | 18× | ± | |
| ↓ fannkuch | 83× | 7× | ± | |
± look at the measurements and then look at the programs.
