Thanks.

>FT_Get_Char_Index()- It takes around 0.005 ms per character.
>FT_Load_Glyph() - It takes around 2.9 ms per character.

Hmm. In next, could you check if hinting affects the speed?
hinting module can be disabled by commenting out 2 lines in
module.cfg:

  # FreeType's auto hinter.
  HINTING_MODULES += autofit

  # PostScript hinter.
  HINTING_MODULES += pshinter

If hinting is not important factor, the next candidate would
be the outline calculation of TrueType font. Could you check
the time to load an embedded bitmap glyph?
