*Just a user impresion:

I have noticed sensible speed up changing from a incomplete icon theme (wasp), 
to crystal. I say really sensible, before I saw the konsole icon bouncing at 
the cursor, now appears almost instant.

And again there was another speed up when I merged hicolor and locolor into 
crystalsvg and linked all folders to one.

Mental note: Write down this in the wiki at the performance tips.

*Now a proto-developer thinking:

I think a pixmap shared memory system is great. 99.9% of apps does not modify 
icons, just display it. So the memory usage can be reduced. And speed too, 
because apps do not need to convert png -> pixmap.
