Hi all, I am trying to find out why one of my projects suffer perfomance declines.
I opened an issue around the problem https://issues.apache.org/jira/browse/FOR-1157 and added some testing file to https://svn.apache.org/repos/asf/forrest/branches/dispatcher_rewrite/FOR-1157 Both wars are basically the same but have some minor difference, mainly the dispatcher library and its dependencies. However I debugged both versions and tested with different tests. The most important match I am debugging is the following: <map:match pattern="**.html"> <map:generate src="lm://resolve.structurer.{1}" type="jx"> <map:parameter name="lenient-xpath" value="true"/> <map:parameter name="getRequest" value="{1}"/> <map:parameter name="contextPath" value="{request:contextPath}"/> <map:parameter name="getRequestExtension" value="html"/> </map:generate> <!-- 1) <map:serialize type="xml"/> --> <map:transform type="dispatcher"> <map:parameter name="cacheKey" value="{0}"/> <map:parameter name="validityFile" value="lm://resolve.structurer.{1}"/> <map:parameter name="request" value="{1}"/> <map:parameter name="type" value="html"/> </map:transform> <!-- 2) <map:serialize type="xhtml"/> --> <map:transform src="lm://hooks-to-html.xsl"/> <!-- 3) <map:serialize type="xhtml"/> --> <map:transform src="lm://namespace-stripped"/> <!-- 4) <map:serialize type="xhtml"/> --> <map:transform src="lm://strip-dispatcher-remains-html.xsl"/> <map:serialize type="xhtml"/> </map:match> In one test I cut the pipeline after the generator (1) and the result is surprising. Since there is NO difference between the old and new version in the generator I was awaiting that the performance should be the same. But 55,5 (new) vs. 64,5 (old) are not even close to be the same. I do not see any reason for performance penalty since I am not actually testing my development but a general component that did not changed at all. Has anybody an idea what the reason for the performance decline can be? salu2 -- Thorsten Scherler <thorsten.at.apache.org> Open Source Java <consulting, training and solutions> Sociedad Andaluza para el Desarrollo de la Sociedad de la Información, S.A.U.
