Created attachment 30386 [details] patch The problem appears in version 2.9 and in revision 1489451. I attached a one-line patch that fixes it. In method "Data.append", the loop over "dHeaders" should break immediately after "valid" is set to "false". All the iterations after "valid" is set to "false" do not perform any useful work, at best they just set "valid" again to "false". Method "include" in class "ClassFilter" has a similar loop (over "pkgs"), and this loop breaks immediately after "inc" is set to "true", just like in the proposed patch. Other methods (e.g., "Copy.keepOnlyAncestors", "JMeterThread.getSampleListeners", "HTTPSamplerBase.getSendParameterValuesAsPostBody", "LogFilter.incFile") also have similar loops with similar breaks, just like in the proposed patch.
Well spotted; thanks for the patch! URL: http://svn.apache.org/r1489490 Log: wasted work in Data.append() Bugzilla Id: 55056 Modified: jmeter/trunk/src/jorphan/org/apache/jorphan/collections/Data.java jmeter/trunk/xdocs/changes.xml
