Subject Re: Axis2 - Rampart performance

Hi Rajan,

See http://www.ibm.com/developerworks/java/library/j-jws6/index.html

WS-Security overhead is very high, and you're best off limiting its use 
for high-volume web services to cases where it's really needed. And it's 
not just Axis2/Rampart that has this kind of overhead - the second next 
article in my series will be out around the end of the year, comparing 
Sun's Metro and WSIT WS-Security performance with Axis2 and Rampart.

Incidentally, I have a 2- or 3-day class on Web Services Security which 
covers options and tradeoffs, with the goal of educating architects and 
developers to understand how to configure and use both transport layer 
security (TLS AKA SSL) and WS-Security for their service. This class 
includes looks at performance issues. I haven't included the description 
for this class on my web site yet (updating the site always seems to be 
at the bottom of the stack...), but if anyone's interested contact me 
directly for details.

  - Dennis
