[jdom-interest] does jdom perform well ?

[biglaughing]

Hi,
It is very easy to manipulate XML using JDOM.But,I have just read a
document :
http://www-106.ibm.com/developerworks/xml/library/x-injava/index.html

that document is written in 2001. I want to know whether JDOM performs
well.I want to use org.jdom.Document to be my middle-container of XML
document.I do need performence very much.

any suggestion is welcome :P

waiting for reply
