Ouch.  `FT_Get_Name_Index' is quite a slow function, indeed, so
caching its results would speed up things a lot.

Note that speeding up the function itself was never on my radar – in
all the years I'm working on FreeTpye there was not a single request
to do so, IIRC.  Modern fonts use the SFNT container format, centered
around glyph indices, not glyph names.  In other words, looking up
glyph indices from glyph names is not a central function in most
cases.

I will check whether I can improve that in FreeType.
