Gonzalo Vasquez commented on FOP-2314:
--------------------------------------

Great! Hope to hear some more results from the tests soon!

Regarding the note: can you please provide some pointers to replacing the svg 
rectangles with fo based ones?

>             Project: Fop
>          Issue Type: Improvement
>          Components: svg
>    Affects Versions: trunk
>         Environment: Tested on Mac OSX 10.9, Java SE 7 (1.7.0_04)
>            Reporter: Gonzalo Vasquez
>            Priority: Minor
>              Labels: performance
>         Attachments: SimpleSVGUserAgent.java.patch, sample.fo

> After having profiled an application I'm coding, and having detected hotspot 
> methods, I've come across with a few suggestions por performance improvement 
> which actually have worked in my environment.
> Changing the referenced method to the following code makes the small trick:
> From:
>     public String getXMLParserClassName() {
>         try {
>             SAXParserFactory factory = SAXParserFactory.newInstance();
>             return factory.newSAXParser().getXMLReader().getClass().getName();
>         } catch (Exception e) {
>             return null;
>         }
>     }
> To:
>     private static final String xmlParserClassName;
>     static {
>         String result;
>         try {
>             SAXParserFactory factory = SAXParserFactory.newInstance();
>             result = 
> factory.newSAXParser().getXMLReader().getClass().getName();
>         } catch (Exception e) {
>             result = null;
>         }
>         xmlParserClassName = result;
>     }
>     public String getXMLParserClassName() {
>         return xmlParserClassName;
>     }
> Could this be added as a patch to the trunk please?
