The new Parser seem to be better:

time makeinfo ~/src/texinfo/texi2html/test/manuals/texinfo.texi

real    0m0.930s
user    0m0.448s
sys     0m0.028s

time perl -w -x -I ~/src/texinfo/tp/ ~/src/texinfo/tp/structuring.pl 
~/src/texinfo/texi2html/test/manuals/texinfo.texi > res.txt

real    0m4.646s
user    0m4.528s
sys     0m0.056s

With the caveat that the time will be more than that, something
like twice, when it is finished.  So more like 20 time slower.
