No comment on your actual question, but this isn't a great benchmark. 
You want to use a variety of glyphs (or texts!) to exercise the glyph
cache. Useful parameters are active glyph complement (~50 for alphabetic 
scripts, vs ~1000 for CJK) and glyph size (very large glyphs don't occur 
very often, but the definition of "large" is different for printing and 
screen rendering). Likewise, switching fonts several times helps test 
the font loader, especially with CJK and "unicode" fonts.

FWIW,
