[ft] FT_Load_Glyph() slow?

I'm currently using the following functions to load glyphs:
FT_Get_Char_Index()
FT_Load_Glyph()

We noticed our rendering was slow, so we instrumented around these two calls. 
We're running on a 32 bit processor, but was still surprised to find that 
FT_Load_Glyph() was taking 500ns. Is this a known issue? Is there a way to 
speed this up? Maybe use FT_New_Memory_Face()? If so, a pointer to an example 
would be greatly appreciated.
