Hi,
We are running Cocoon2.1.3 (XML/XSLT Framework from apache) in WAS5 and had
to do some configuration tricks to improve the performance of the
transformations.
If your application is running inside a webcontainer you have two
possibilities:
1) Put your XSLT engine (I would recommand Saxon6.5.3 - the 7.x versions
won´t work with jdk .1.3.x) inside your WEB-INF/lib
configure your app to use this jar
if this is not possible
2) put the saxon jars in the classpath of your serverconfigfile, it will be
loaded on startup of your WAS test environment
maybe your servlet needs an init-param to look for it, but that depends on
your app.
if you have any problems give me some details about your app / framework
regards
Manfred

Thema: RE: Antwort: [xsl] real XSLT performance
Manfred,
For now I could do the configuration in WSAD 5.1 if you give me a hint.
That will at least establish that XSLT <em>can</em> be done with some
reasonable performance in a WS environment. Then I can do the WAS
configuration later.
Thanks for your help.
Stuart Zakon

Hi Stuart,
The default xslt engine is a quiet old xalan version. When you ask for the
vendor (as Michael suggested) you will get Lotus Group Foundation.
This xslt processor is very slow!
Are you running your templates in a web container?
There are some tricky ways to tell websphere it should use another xslt
engine. Its easy to configure in WSAD but not that easy in your production
environment.
Which OS are you running (e.g. WAS on hostsystems is very different to the
AIX version) Are you using the WAS 5.1 EE?
regards
Manfred

Thema: [xsl] real XSLT performance
I am using JAXP Templates for performance and getting excellent results
under the Resin servlet engine. It is highly scalable with my stress tests
going from 5 to 100 concurrent threads with several steps in between.
However, when I move the test over to WebSphere 5.1 and WSAD 5.1, it
doesn't
scale well beyond 5-10 concurrent threads. Which XSLT engine does WAS 5.1
use? Does anybody know of a high-performance XSLT engine for WebSphere?
Thanks,
S. Zakon
