As a followup to the list Eli suggested, this works for me on Windows
10:

  (set-frame-font "DejaVu Sans Mono-9" nil t)
  (dolist (fontspec-targets
           '(;; Latin Extended Additional block (not supported by DejaVu Sans Mono)
             (("Liberation Mono"    . "iso10646-1") (#x1e00 . #x1eff))
             ;; Other scripts
             (("DejaVu Math Tex Gyre" . "iso10646-1") mathematical)
             (("Segoe UI Symbol"    . "iso10646-1") braille symbol)
             (("Myanmar Text"       . "iso10646-1") burmese)
             (("Ebrima"             . "iso10646-1") ethiopic)
             (("Microsoft Himalaya" . "iso10646-1") tibetan)
             (("Leelawadee UI"      . "iso10646-1") khmer thai)
             (("Gadugi"             . "iso10646-1") canadian-aboriginal cherokee)
             (("Nirmala UI"         . "iso10646-1") bengali devanagari gujarati
              kannada malayalam oriya sinhala tamil telugu)))
    (dolist (target (cdr fontspec-targets))
      (set-fontset-font "fontset-default" target (car fontspec-targets))))

That reduces the delay in showing the HELLO file from approx 20secs to
approx 3secs on my box.
