That's because there is some breakage in the design of the expat/perl linkage.
In my tests, given a file of  a couple of meg, perl can read it in under
a second, xmlwf (i.e. raw expat) in an almost unmeasurably-short time, and
XML::Parser takes 10 seconds plus.  This is just a bug and will be fixed.
