Absolutely. Which is why I posted my numbers and my code. The other thing to consider is that Perl is still a compile-on-the-fly system. I hope Perl 6 keeps this aspect of Perl instead of moving to a more Javaesque development environment. This means time spent doing dataflow analysis to help with register allocation is going to eat into perceived execution speed. Parrot might fly, but if the Perl 6 compiler is slow, the user experience will be poor. Hopefully the compiler will run quickly and generate decent code. A separate super-optimizing compiler can be used for important things like CGI.pm. ;) - Ken
