Thanks for your help. I tried Benchmark but the results seem not reliable: cmpthese( -5, { a => sub{$x*$x}, b => sub{$x**2} } ); outputs: Rate b a b 3858660/s -- -19% a 4757428/s 23% -- cmpthese( -5, { a => sub{$x**2}, b => sub{$x*$x} } ); outputs: Rate b a b 4401295/s -- -14% a 5141629/s 17% -- perhaps I missed something ? -- Gérard -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
