When creating info files for the GNU Emacs Lisp Reference Manual (app-doc/elisp-manual-24.3), I noticed that makeinfo 5.1 is very slow:

With makeinfo (GNU texinfo) 4.13:

   $ time makeinfo elisp.texi 
   real    0m1.677s
   user    0m1.498s
   sys     0m0.062s

And with makeinfo (GNU texinfo) 5.1:

   $ time makeinfo elisp.texi 
   real    1m10.085s
   user    1m9.594s
   sys     0m0.352s

That's a factor of more than 40.

it's a feature!

  The Perl texi2any/makeinfo both replaces and is intended to be (for
  all practical purposes) upward-compatible with the C makeinfo.  It has
  many new features not in the C makeinfo.  For example, cross-manual
  references are now fully supported, and allows for extensive
  customization of the HTML output.  See the `Generic Translator
  texi2any' chapter in the manual (among other places) for more about
  this reimplementation.
  
  The new program is, unfortunately, noticeably slower at present than
  the C program was.  We hope all the many improvements make the new
  version worthwhile for users nevertheless.
