Not answering the original question, but want to share a similar question that I had in the beginning of Axis2 design - if the entire content of a SOAP message is meant for consumption at various phases by various components, the round-trip performance of message parsing by StAX shouldn't be higher than that of SAX parser, at least theoritically. After all, whether it is pull or push, I think every xml chunk in the SOAP message has to be consumed somewhere during the message processing.
I'm also delighted by the performance of Axis2 (great job folks), and also like to know the reasons, probably not related to StAX parser. thanks Venkat On Mon, Jun 16, 2008 at 4:07 PM, <[EMAIL PROTECTED]> wrote: > Dear Keith, > > Thanks for your reply. > We're aware that Axis2 is much faster than Axis1.X and we have conducted > similar tests as described in the articles. > Our question is, is the performance gain in Axis2 is due to the use of StAX > API?
