You have long lost me on your discussion about Emacs internals, but I should 
just like to say that the unicode-fonts package from 
https://github.com/rolandwalker/unicode-fonts has fixed all these delays for me.

As far as I understand, this package maps Unicode blocks to specific fonts.  I 
presume that Emacs would otherwise search through all installed fonts for one 
that supports the Unicode character that needs to be drawn, and that the 
explicit mapping prevents Emacs from doing that.

Seems that Eli was right with his “Fix your font configuration” remark.

Thanks for your help and your effort!
