[Qt-interest] Prerenderend fonts slower...

[OS Prog]

Hi,

I'm running Qt 4.5 on embedded platform and I was thinking if I'm
using prerendered fonts, like 'helvetica 18' will be faster than
'arial 18' (which is not qpf).
In first case font.exactMatch() returns 1 and the  execution time is
~10% slower than the second case, where font.exactMatch() returns 0.
I'm drawing the fonts with QPainter's drawText() method.

Why? The prerendered fonts drawing should be faster, shouldn't it?

Regards,
Nik
