FWIW, I'd be in favor of raising `read-process-output-max' to something
like 40960 (as Eli suggested in this thread), or perhaps some power of 2
close to that like 32768 or 65536.

This is based on it being seemingly faster in the benchmarks in this
thread, and me having used that locally for 2-3 years and noting no
adverse effects.

(I didn't review patch 1 and 2, so no opinion on those.)
