On a default Cocoon installation on JDK 1.4, the commons-httpclient used by HttpProxyGenerator will use Java 1.4 Logging unless otherwise configured (or unless log4j is present). The implementation of the Jdk14Logger in commons logging is however extremely slow, due to the fact it will each time create an exception to extract the callers method name, even when logging is not enabled.
The simple solution is to just drop log4j.jar in WEB-INF/lib, or configure commons-logging in another way. I did some tests using JMeter and HttpProxyGenerator, and it's more than two times faster when not using Jdk14Logger (average over 1000 requests: 28 ms vs 81 ms). I've submitted a patch to commons bugzilla (nr 18184) to address this. -- Bruno Dumon http://outerthought.org/ Outerthought - Open Source, Java & XML Competence Support Center [EMAIL PROTECTED] [EMAIL PROTECTED]
