Description
Flamegraph of a Google Sans builds reports `norad::glyph::Glyph::load (2,878 samples, 24.86%)`. This is apparently because parsing is hard work, `norad::glyph::parse::GlifParser::parse_body (2,682 samples, 23.16%)`.
fontc will issue per-glyph reads from threads running GlyphIrWork so this should parallelize. Still, one has to wonder if this could be sped up.
