This page give details related to the setup sustaining myxwiki.org which is used by the XWiki Dev Team as a real life test of a very big XWiki instance.
Numbers
MyXWiki.org is a single XWiki instance currently containing 481 wikis.
Container and hardware
- maximum memory allocated to the JVM: 2048m (not huge but one of the points of MyXWiki.org is to make sure XWiki is not too bad at scaling it term of memory)
- 5 vCPU of 2.8GHz
- installed/upgraded using XWiki Debian packages
- MariaDB 10.3
- Tomcat 9
Performance related customizations
Remote Solr instance
The kind of volume myxwiki.org have to deal with does not fit well with the Solr embedded mode so we had to use a dedicated Solr standalone instance located on a different server.
- maximum memory allocated to Solr JVM: 2048m
- 2 vCPU of 2.8GHz
xwiki.cfg
- xwiki.store.cache.capacity=800
- xwiki.store.migration=0 (checking migration status takes a very long time with so many wikis and would impact restarts too much)
- xwiki.stats=0
xwiki.properties
- notifications.rest.poolSize=4
hibernate.cfg.xml
- <property name="hibernate.dbcp.maxTotal">200</property>
- <property name="hibernate.dbcp.maxIdle">20</property>
Other interresting customizations
xwiki.cfg
- xwiki.virtual.failOnWikiDoesNotExist=1
- xwiki.virtual.usepath=0
- xwiki.authentication.cookiedomains=myxwiki.org
xwiki.properties
- wiki.alias.suffix=myxwiki.org
- logging.deprecated.enabled=false
