Subject (performance) problem on weblogic 7
Date Tue, 16 Sep 2003 12:25:58 GMT
Hi,

we encounter a performance problem running Cocoon deployed on a Weblogic Server.  As the same
small application is running fine on the supplied jetty-engine the problem seems WLS related.

Even a relative simple resource request as  http://xml.ftd.de/cocoon/mobile/logos/ftd_239x37.gif
takes more than a second to fulfill although cocoon states to need less than 40 milliseconds
(log excerpt below).

It seems as there is some penalty per request before cocoon is involved but I don't know where.

I'am started with a WLS-domain right out of the box (wizard), added an exploded cocoon-webapp,
modified cocoon.xconf to include a datasource (not involved here) and modified logkit.xconf
for a more verbose logging.  Later on I added a weblogic.xml with pageCheckSeconds and servlet-reload-check-secs
parameters.  Putting the xalan and xerces in the classpath makes no difference

Any hints where to look next are greatly appreciated!

Regards,
Christian
