Laura Bailey commented on RF-8425:
----------------------------------

Documented as a fixed issue in WFK 1.1 release notes:
            Repeated calls to <methodname>RendererBase.getResource(String resourceURI )</methodname>
            during the constructor of <classname>ToolTipRenderer</classname> had a negative
            effect on application performance because the 
            <methodname>ToolTipRenderer.getRenderer(UIToolTip toolTip)</methodname>
            method did not cache subclasses. Subclasses are now cached, drastically improving
            performance.

> We have used rich:tooltip in a lot of places within our application. And while profiling, we came to a bottleneck caused by repeated calls to RendererBase.getResource(String resourceURI ) during the constructor of ToolTipRenderer. I think the main issue is the ToolTipRenderer.getRenderer(UIToolTip toolTip) method never caches the subclasses and thus created a lot of HtmlToolTipRendererBlock, HtmlToolTipRenderer objects, and calls to RendererBase.getResource(String resourceURI ). We've overriden the renderer in our environment to use something that caches the subclass and it improved performance a lot.
