[Freetype] loading and rendering time

[Nir Rostoker]

Hi !

I have done some tests to find out how long some actions in FreeType take. 
1. Working with the same font I have measured the time of loading and then
rendering a Glyph both when the font was from ROM (using FT_New_Memory_Face)
and both 
    when the font was from a file. I haven't noticed time difference, even
though I had expected that using a file would take much longer. 
    Is it due to a smart algorithm that read chunks from the file ? does
anyone can explain this ?


2. Moreover, I changed the size of the raster pool (from its default  size
to a size very near to its minimal limit - around 4.5-5KBytes), I haven't
noticed a difference in the
    rendering time, even though I have expected it to be significantly
slower.

The time measurements were conducted by me in various ways (different
timers...) to make sure they are accurate. 


Thanks, 
Nir
