[jboss-dev-forums] [JBoss ESB Development] - Performance: Extracting security credentials from requests

[beve]

As part of the performance work that David and I are working on I've been looking into ways to improve the performance when we extract security credentials from different message and transport protocols.

Currently we are using Smooks and the reason for that choice simply that was the quickest for me to implement. 
I've now looked at using Stax and also at SXC (http://sxc.codehaus.org/Home)

I've taken one of the extractors which extract the Username element data and the Password elements data from a SOAP Security Header. The SOAP message is a String in this case and not a SOAPMessage object instance.

Following are the result that I've gathered:

Smooks
======
Test: WSSecurityInfoExtractorUnitTest.extractUserPassSecurityInfo
1ms     1969497ns
1ms     1985770ns
2ms     2154726ns
2ms     2325567ns
2ms     2807360ns
3ms     3157355ns
5ms     5156815ns
6ms     6649339ns
7ms     7066943ns
11ms    11248229ns

SXC
===
Test: WSSecurityInfoExtractorSXCUnitTest.extractUserPassSecurityInfo
16ms    16576305ns
18ms    18043196ns
23ms    23826942ns
24ms    24942720ns
28ms    28823322ns
31ms    31506149ns
32ms    32187070ns
45ms    45235491ns
59ms    59891821ns
93ms    93950116ns

Stax
====
Test: WSSecurityInfoExtractorStaxUnitTest.extractUserPassSecurityInfo
0ms     641808ns
0ms     647256ns
0ms     662552ns
0ms     666883ns
0ms     675334ns
0ms     678756ns
0ms     720663ns
0ms     743293ns
1ms     1771975ns
11ms    11028217ns

So I think Stax is the way to go here. If no one objects I'll create a Jira for this.
