You should add spaces around the / operator as well (i.e. defaultCacheSize / 8)
Also, given that we're dividing you should use qMax() to ensure that the pixmap cache's maxCost has a minimum (perhaps 16 KiB).</pre>

For now the pixmap cache gets a maximum size of 10% from the shared data cache on disk. Is this a good value or should it be something different?</pre>
