Or, why not just set `font-lock-maximum-decoration' to 2? This runs at
~2½ times the speed of the default fontification (measured by scrolling
all the way through .../src/xdisp.c), and is barely slower than
`font-lock-maximum-decoration' being set to 1 (which merely fontifies
comments and strings).
Fair warning: setting `f-l-m-d', and making the setting work, is
difficult (see bug #23783). One way is to do
M-: (font-lock-refresh-defaults)
in a buffer after changing `f-l-m-d'.
