All interpreted languages are slow, because you need CPU cycles to 
interpret instead doing the job. The only important question is: is it 
fast enough for your use case? That's an question which nobody can 
answer for you.

You can mix most interpreted languages with native libs so you can split 
the thing. And if it's still too slow you should use only something like 
C or C++.

And there are some tradeoffs you can make: Native speed with long and 
unflexible code (C/C++) vs. optimizing your whole system (caching, 
avoiding execution of code) and flexible short code.

The winner in speed is always compiled native code. So you have to know 
your requirements.
