Major parts of Perl are written in C and optimized all the way.  Hash 
lookups and regular expressions, for example.

Many Perl modules are written as interfaces to compiled code.

I have a project that can do a lookup in 3 microseconds, using a series 
of cache aligned, prefetched b+trees.  It takes a *lot* longer in pure Perl.

I did make a Perl interface to it of course. :)
