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? | ||||

| ↓ fannkuch | 62× | 1/3 | 1/2 | |
| ↓ spectral-norm | 145× | ± | 1/2 | |
± look at the measurements and then look at the programs.
