--- Comment #18 from Antoine Levy-Lambert <[email protected]> --- I created this build file to test : <project name="doit"> <echo>ant.version=${ant.version}</echo> <script language="javascript"> <![CDATA[ for (i=1; i<=1000; i++) { exec = doit.createTask("exec"); exec.setExecutable("attrib"); exec.createArg().setValue("-r"); exec.createArg().setValue("doit.xml"); exec.perform(); } ]]> </script> </project> --- I ran the build file on Windows 7 with JDK 1.7 using this script : export ANT_HOME=c:/opt/apache-ant-1.7.1 ant -f doit.xml export ANT_HOME=c:/opt/apache-ant-1.9.2 ant -f doit.xml export ANT_HOME=c:/opt/apache-ant-1.9.3 ant -f doit.xml ---- here is the output : $ ./doit.sh Buildfile: doit.xml [echo] ant.version=Apache Ant version 1.7.1 compiled on June 27 2008 BUILD SUCCESSFUL Total time: 8 minutes 6 seconds Buildfile: C:\dev\54128\doit.xml [echo] ant.version=Apache Ant(TM) version 1.9.2 compiled on July 8 2013 BUILD SUCCESSFUL Total time: 14 minutes 50 seconds Buildfile: C:\dev\54128\doit.xml [echo] ant.version=Apache Ant(TM) version 1.9.3 compiled on December 23 2013 BUILD SUCCESSFUL Total time: 8 minutes 5 seconds The test build file as you can see runs 1000 times attrib on a single file. The performance of Ant 1.7.1 and Ant 1.9.3 in this test are the same, Ant 1.9.2 is much slower. Is there something specific to the command that you are running which is such that it is slow under Ant 1.9.3 ? Did you set ANT_HOME to point to the installation of Ant 1.9.3 when you tested it ? -- You are receiving this mail because: You are the assignee for the bug.
