Started with 5.0.3. The upgrade to 5.1 went splendid, performance was fine.
But to upgrade to any version > 5.2, 5.2.2, 5.3, 5.4.5, 6.1 is very slow three times slower to render the home page. Subsiquent visits to the page are equally slow. I thought it might be a problem with the upgrade, but I did a clean install of 6.1 and it is still three times slower than my 5.1 install. ENVIRONMENT SUSE Linux Enterprise 11 SP3 (SLES 11.3) Java Version: java version "1.7.0" Java(TM) SE Runtime Environment (build pxa6470sr7fp1-20140708_01(SR7 FP1)) **IBM J9 VM (build 2.6, JRE 1.7.0 Linux amd64-64 Compressed References 20140627_204598 (JIT enabled, AOT enabled) [notice it's IBM JAVA] java-1_7_0-ibm-1.7.0_sr7.1-0.5.1 java-1_6_0-ibm-1.6.0_sr16.1-0.3.1 java-1_7_0-ibm-devel-1.7.0_sr7.1-0.5.1 rpm -qa | grep tomcat tomcat6-jsp-2_1-api-6.0.41-0.43.1 tomcat6-6.0.41-0.43.1 tomcat6-lib-6.0.41-0.43.1 jakarta-commons-pool-tomcat5-1.3-1.29.2 jakarta-commons-dbcp-tomcat5-1.2.2-88.34.4 tomcat6-servlet-2_5-api-6.0.41-0.43.1 jakarta-commons-collections-tomcat5-3.2-88.34.2 Mysql mysql-5.5.39-0.7.1 libqt4-sql-mysql-32bit-4.6.3-5.29.2 libmysqlclient15-5.0.96-0.6.13 mysql-client-5.5.39-0.7.1 mysql-connector-java-5.1.6-1.27 Tomcat Options: CATALINA_OPTS=" -Xms800m -Xmx800m -XX:MaxPermSize=196m -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100" Also tired lowering the Xms (as recommended by IBM Java folks) but did not help CATALINA_OPTS=" -Xms256m -Xmx800m -XX:MaxPermSize=196m -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100" The part that is most puzzling is that a fresh install of 6.1 is still sooooo much slower. Tomcat uses near 100% of cpu for any page read, and mysql uses 25% for any page read The tomcat logs don't have any errors (I turned the log4j debugging up to see if I could catch something odd) Any Ideas. I'm fresh out. -- Mark Gardner _______________________________________________ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
