Caching, caching, caching.  Especially loading a hinted TrueType glyph
needs a lot of resources.  I really doubt that there is any
possibility to make it really faster, given that David is a specialist
for exactly such things.  Note, however, that not all compilers
optimize in the same way, so you should play with your optimization
options, together with a lot of profiling.
