Some time ago we also had performance issues. In our case it was 4GB + 2 CPU, 32 bit virtual machine running on CentOS 5.4. Database (MySQL 5.0.70) was on the same server. Tomcat 6.x. We had ~25 active users of wiki and ~1.5K documents. In addition we had our Jenkins, Sonar and Archiva running on the same Tomcat. This has led to high memory usage (especially perm gen which was set for 512M) and actually we have allocated all the memory we could under 32 bit. But still responsiveness grew slower with time (due to often GC) and eventually we got OOM. Problem was solved by migrating to 64 bit Centos 5.8 and setting -Xmx4096M -Xms4096M -XX:MaxPermSize=512M We have also increased cache capacity from 500 to 1000 documents Hope this info helps :) @XWiki-committers: I think it would be a good idea of publishing system requirements depending on the number of concurrent users and amount of documents in the database. -----Original Message----- From: users-bounces(a)xwiki.org [mailto:users-bounces@xwiki.org] On Behalf Of ThomasvdW Sent: Tuesday, February 05, 2013 16:13 PM To: users(a)xwiki.org Subject: [xwiki-users] xWiki server is slow Our xWiki server is very slow Our server is running on TomCat version 6 The database is a Windows 2003 MySQL it has 4GB Ram and 2 processors Does anybody know a solution? -- View this message in context: http://xwiki.475771.n2.nabble.com/xWiki-server-is-slow-tp7583722.html Sent from the XWiki- Users mailing list archive at Nabble.com. _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users
