Subject Re: Using XML security slows down the Axis Call
Date Fri, 27 Feb 2004 19:56:15 GMT
Some time ago (6 weeks or so) I did some performance measures (WSS4J has
timing logs build in) and we see here that Verification/Signature
is real time consuming, followed by public KEy encryption, followed
by symmetrical encryption....this ordering comes with no surprise.

Only the real time consumed is quite high.
