XOM API for Processing XML with Java

[csad7 AT t-online.de]

hello,
are there any performance comparisons between lets say XOM and 
dom4j/JDOM etc?

I try to persuade some colleges at work to use XOM instead of dom4j 
(which has bitten some projects with some nasty details mostly issues 
about whitespace handling) but they question the performance of XOM.

Googling did not bring any real help, so I'd think I'll ask here...

thanks a lot
