Sample XSL file to demonstrate the problem

I have recently been involved in the development of an XML/XSLT application. Unfortunately, we have found that performance is poor on webkit based browsers.

We were able to create a simple XSL that demonstrates the problem:

http://www.malch.com/xml/test.xsl

Together with some XML data to feed it:

http://www.malch.com/xml/test.xml

Here are some approx CPU times required to complete the transform 10 times on various browsers:

Chromium (latest dev version): 29 secs
Safari 5.0.3: 33 secs
Firefox 4 Beta 7: 18 secs
I.E. 9 Beta: 9 secs

All timings on the same system running Win 7 x64.

Overall, the webkit based browser performance is quite sluggish compared to Firefox and IE 9 which is a shame :-(

Any improvement would be most welcome.
