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 ?
