Oh, that's very interesting!
So first of all let me clarify that I was seeing multiple-second delays
with primitive 103 enabled, but mere multi-hundred-millisecond delays
with it disabled. Does the primitive touch the cache?
I'll explore different settings.
Is it recommended to increase the cache size after importing a new font,
or is it something that should maybe be a bit larger by default anyway?
