[xwiki-users] Xwiki performance

Hello, I need to migrate my Xwiki in data center, on a Tomcat 7.0.47server with 10Go RAM. I use postgreSQL server but filesystem based attachment store. I read with attention http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Performances page. This is still adapted on 6.2 version? Have you some more tips to increase XWiki's 6.2 performance? You indicate "Try not to ge beyond 1024MB since adding more memory means more GC time and thus lower performance." With 6.x I needed to use this parameter (without it, Xwiki crash): JAVA_OPTS="-server -Xms1724m -Xmx1724m -XX:PermSize=256M -XX:MaxPermSize=512m -Dfile.encoding=utf-8 -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100 -Dhttp.proxyHost=xxxxx -Dhttp.proxyPort=xxxx" Do you have a filtered table containing admins system config and perf? Something, like: PowerEdge 2950 | 16Go RAM | Wheezy | Tomcat 7.0.47 | JAVA_OPTS="-server -Xms | ... | Perf: good Of course, perhaps it is a security hole to display too much, but tomcat conf is a minimum? WDYT? Thxs Pascal B
