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? | ||||
