As far as I remember, the text system uses IMP caching at two

GSHorizontalTypesetter and in NSGlyphGenerator. These two are central

method calls that had been optimized into function calls don't make

much difference any more. At least at the time when the optimisation

done there were hard figures that suggested this to be worth while.
Do you have any numbers that say so or is this just general ranting
against premature optimisation? The later I support whole heartedly.
Mainly it's a general rant; I haven't looked closely at the text
system for a little while, but last time I tried I found it completely
incomprehensible and most of the things that were causing that seemed
to be microoptimisations on poor algorithms, which could have been
offset by using better algorithms.
