The reason is that we're retrieving the icon path every time to see if it's available (because it goes through aaaaaaall of the themes' directories to find the best available icon).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch adds a dictionary in the KIconLoader so that we can cache for the icons we already found, clears it when the theme changes.
Also we're construct the same sizes list every time, now we're always returning the same list.</p></pre>

It doesn't show a big problem in the same use-case in kdevelop anymore (99.5% of hits).</p></pre>
