It really depends. The question really should be, "Is Perl 6 fast enough?" For my purposes, the answer is almost always yes. I can imagine some applications where the answer would be no, but then I would probably be looking at C/C++ for a solution, anyway. Language bench-racing has really begun to look counter-productive to me.

Someone once posted code that they had written in both Perl 6 and C/C++. The Perl 6 code was shorter, arguably easier to understand, and they said it was also faster for their data.

My guess would be that the strings had to be copied more often in the C/C++ code.
