XDrawString draws bitmap fonts only, try to use Xft with 
scalable/antialiased fonts and you'll see the difference... If you have 
a  bottleneck in drawing text - use PangoX backend or just raw X lib 
calls (you'll a HUGE pain in mixing glyphs from different languages).
But 600 times you mentioned - are you kidding ? What hardware/X 
server/Xft/Xrender/fontconfig/freetype/Gtk/Pango/fonts are you using ? 
Some time ago when I was stuck on this I have 10-20 times on 
non-accelerated hardware.
