web crawler in python or C?

[abhinav]

It is DSL broadband 128kbps.But thats not the point.What i am saying is
that would python be fine for implementing fast crawler algorithms or
should i use C.Handling huge data,multithreading,file
handling,heuristics for ranking,and maintaining huge data
structures.What should be the language so as not to compromise that
much on speed.What is the performance of python based crawlers vs C
based crawlers.Should I use both the languages(partly C and python).How
should i decide what part to be implemented in C and what should be
done in python?
Please guide me.Thanks.
