And here's an update comparing "Christmas Perl6", aka v6.c, aka rakudo star 2016.01.1 to Strawberry Perl 5.16.3, using a bat script on Windows 7: 
echo %time% - perl5
call c:\strawberry_perl\portableshell.bat -E "my $s; for ( 1..1000000 
+) { $s+=1/$_**2 }; say $s"
echo !time!

echo %time% - perl6
call perl6 -e "my $s; for ( 1..1000000 ) { $s+=1/$_**2 }; say $s"
echo %time%

Note I'm using a million iterations to make the times more accurate to compare. The output was: 
14:03:07.14 - perl5
1.64493306684877
14:03:07.64
14:03:07.65 - perl6
1.64493306684877
14:03:19.05

So, perl5 took .5 sec and perl6 took 11.4 secs, making perl6 almost 23 times slower than perl5. I really hope this is improved on in subsequent releases of perl6. John
