Comment(by yasuimao@…):

 I tested this with 2011/01/04 nightly.  This time, I changed the length of
 the text.  I used the same original text and deleted later paragraphs to
 shorten it.

 {{{
 MacRuby 0.9 2011/01/04 nightly - 1548 words

 }}}

 This build is faster than the one I tested last time (2010/12/24), but
 still much slower than before.

 Just to campare, I run the same test with 2010/12/17 nightly.
