Yes this language is very slow, but frequently this isn't a problem, because you are using fast functions/libraries written in C, or you are doing I/O bound operations. And Psyco, numeric/numarray, ShedSkin can help in some other cases (Pyrex and other solutions allow you to mix in lower level languages). If you are looking for pure algorithmic speed you probably have to go look for other languages, like C, C++, Ocaml, typed Lisp code, etc.
