Subject Re: Webservice handling consuming considerable CPU (Windows)
Date Wed, 06 May 2009 03:47:26 GMT
I think the main problem here is that we keep creating a new
TransformerFactory instance on each request which causes an expensive
provider search. We can probably cache the TransformerFactory instance
and reuse it on subsequent requests (or maybe even rewrite the code
not to use the TransformerFactory API). Can you please open a bug on
it?

Thanks,
Jarek
