Are the Perl programs faster?
Do the Perl programs use optimized assembly code libraries? Are they small simple programs or very optimized programs? Do the Perl programs use a fraction of the time used by other programs or do they use several times more?
| Perl used what fraction? used how many times more? | ||||
|---|---|---|---|---|
| Programs | Time | Memory | Code | Reduced N |

| ↓ k-nucleotide | 1/5 | 1/2 | ± | |
| ↓ fasta | 1/4 | 1/127 | ± | |
| ↓ sum-file | 1/4 | 1/2 | ± | |
| ↓ reverse-complement | 1/4 | 1/2 | ± | |

| ↓ n-body | 1/3 | ± | ± | |
| ↓ spectral-norm | 1/2 | ± | ± | |
| ↓ fannkuch | 1/2 | ± | ± | |
| ↓ recursive | 1/2 | 1/4 | ± | |
| ↓ nsieve | 1/2 | 4× | ± | |
| ↓ pidigits | ± | 1/11 | 1/2 | |
| ↓ regex-dna | ± | 1/4 | ± | |
| ↓ binary-trees | ± | ± | ± | |
± look at the measurements and then look at the programs.
